Here go to your varieties as follows V for the bank equals 300. B one equals 200. Find a value is 0.75 all rather quality X equals 0.75 the from here here to find V underscored f onda we underscored G in gaps volume steam Underscore i A B W s X equals zero and p equals B one. Really escort G would be While you steam underscore I be less X equals zero X equals one b equals B one. Now when you have these, that's when you have V equals V underscored deaf. Thus quality X star different the volume and finally you have Japanese. For the bank it was one of the volume much bad by density.

Here. You right? The bank. It was 300. We want because 200 s Because they're 475 v underscore f are just right. VF It was the in biz function. While you steam underscore I be ws X equals zero b He was be one and v g Equals are the same exit was one. So from here we comes out to be VF. Thus, it's starred V G minus VF Doing all this, you will find the mass to be 4 51 You know, grab equities option a.

Okay, so we're dealing with systems of linear equations. We have a fruit drink is made by mixing fruit juices. Such a drink is 50% juice to be mixed with another drink that is 30% juice. To get 200 leaders of a drink that is 45% juice. How much of each should be used? Okay, so let's call X the variable for 50% juice. So 50% times the amount of X plus 30% the amount of why we need to get 200 leaders, that is 45% juice. So if it's 200 leaders, that means X plus why is equal to 200? And we need this to be 45% juice. So this is 45% of 200 so X plus y is equal to 200 and then we have 0.5 x plus 0.3 y is equal 2.45 times 200 which gives us 90 so we can solve this Ah couple of different ways. If we multiply the second equation by two two times 20.5 is one. So this would give us X. So we have 0.3 times two is going to give us 20.6. Why? And 90 and 90 is 180. And now we have X Plus y is equal to 200 if we subtract thes so one minus 10.6 is 0.4 this 0.4. Why 200 minus 80 is 20 so 20 divided by 200.4 means why is equal to 50 and if why is equal to 50? That means X is 150. So we can check this by 0.5 times 150 plus 0.3 times 50. Well, give us 90. So we need 50 leaders of why and 150 leaders of X.
