Finance Francine earns 120 dollar
per month more than Rob. If they earn a total of 2,680 dollar per month, how much does Francine earn each month?

We're told that weekly allowance is directly proportional to a child's age. Were given the age of a six year old is receives an allowance of $4.50 and we need to find the allowance that an 11 year old will get. So are direct equation is Y. Is equal to K. Times X. What's mentioned before. Directly proportional is why afterward is X. So we replace, we have our allowance Which is 450 Is equal to a constant proportionality, which we don't know times six. We divide both sides by six, so 450 divided by six comes out to be that K. is 75 cents, So we get y is equal 2.75 times x. So we plug in 114 or X and we get .75 times 11. So an 11 year old gets $8.25.

Clear lines is Dr Capable Snow directly proposed Child's Each. So Let's it, Vicky Alliance were representing it by Why? And the child stays were represented by in terms of X here. So it is given why is directly proportional to X. That is very close to kits We're is the variation costing or proposed in Boston? No further does give it their six year old daughter receives allowance of 4.50 That means at X equals toe 4.5. Little got a six year when accident six years that in that case, the value of why we are having $4.50. Okay, so we should start by this point in this equations of what we're getting. 4.5, that is a closed toe K times off. Six. This gives us the kids 4.5 divided by six. So we should write it as three times. It is 1.53 times it is, too. Which US gays. September 20 We can, right? So the value off cave we have 15 divided by 20. That is five times 35 times for that is three driver for integration Constant. We have treated by wherefore three questions off weekly alliances. What's if the child says it is? Why? Because toe three divided by four times picks? No. Also, we have to find at X equals two. That means when child Syria's 11 year So when x is a living course warning. Why would have three divided by four times 11 which is 33 Divide way for which is 8.25 a Bronx started to divide by four. We should right $8.25. This is an answer. So in this case, Vic Lee alliance that that child get $8.25.

So this question is, is that Kira based on iPhone? Well, so the cost price is to $40 and she gets a Kozmus applause off $160. Now the first question What is our willingness to pay so willingness to pay? Is the sum off okay wanted us to pay? Is this song off the price that she paid? Plus the console myself? Plus so therefore, Myllyla terms So therefore give us or willingness to play pay will be cause to so $40 plus 1 $60 which is $400 now. The next question. If she bought, issued by the iPhone or so now the cost price to be 1 $80. What would be a consumer surplus now if she had bought iPhone herself, for one? Is he a condom? A surplus? Advise the one, etc. Would be 400 unfunded being the willingness to pay minus, um, achy, but it itself and thus to $20. Not the last question. If the price of an iPhone way $500 what would be a consumer surplus now if the price of a Nathan was 500 should not have purchase one because this price so xun porches at 500. Because this price is greater than a willingness to pay, it is greater, um, our willingness to pay no willingness to pay. Remember, it's $400. So she would not have wanted a $500. So should receive no consumer. Suppose, because remember that you wouldn't have to place. How much are we need to pay on you? She don't. We need to pay 400 on the price is 500. Therefore, she won't bite, so that's the answer.

So Tare won some money on a game show. So first she paid half of our winnings and taxes. Then she invested 1/3 at 14% 1/6 at 12%. And after one year, she earned $4000. So we want to determine what her initial earnings were. So this first part is just extra information. Really? They won't really contribute to anything because, well, 1/3 +16 this is just 1/2. So this is the remaining of her earnings. So the only thing we really need to use is how much he invested and how what she heard. So this is going to be simple interest. And we know the amount of money that we're going to occur on or earned is going to be so this is e is equal to our principal investment times. Our rate times our time in the years, all right. And in this case, we're gonna have to equations that we're going to work with. Look, see? So the principal remember is our initial investment and rate is just our percent as a decimal. So for this 1st 1 I call this the one this is going to be equal to Well, the principal was 1/3 of winning, so it's called W winnings. So it would be 1/3 W R rate is going to be 0.14 once recovered, that decimal and in the years is just one. So let's see what that simplifies town too. So one point 14 times are divided by three is 7 50 w. So we end up with 7/1 50 w R earnings on anyone now. What about E too? Well, this is 16 of our winnings for our principal. We're investing in that 12% and this is over a course of one year is well, so 0.12 divided by six gives 1/50 w. Now we are told that her total urn or how much he earned on her investment after one year, was $4000. So we would do 4000 is equal to e one plus you too. Now we can go ahead and sub in these two, so we get or 1000 is equal to 7/1 50 w plus 1/50 w. So adding those together should give us, um well Let's see. So we would multiply this by three like that so it would be 10/1 50 w, which should simplify down two won over 50. So let's just go ahead and move this Appear there are 4000 is equal to 1/15 W Now to get W by itself, we we just need to multiply each side by 50 and then 15 times 4000 is 60,000 so her initial winnings were $60,000.
