So we're giving the speed, print manufacturers ourselves 18,000 I technology printing presses each year. And the variable and fixed costs of network and repairs are given. So the first question wants us to say, he says, should speak, prints, change the new components and show your calculations. So given the question given the the the the table we're giving and the question about giving look, we're going to find armored vans costs over the next year of choosing the new components. So the relevance cost over the next year of choosing the new compliments Zico to $70 Not supplied by 18,000 units. And as it costs one million to 60 1000. So therefore the cost of saving the cost of quality items. I'm sorry. And the savings in reward coasts. So we're going to have the cost of quality items. Then the savings in your war costs. So We're going to have $79 multiplied by 14,000. We work hours And this is 1, 1 server, six 000 And then savings. We have savings in customer support hours, suppose costs and then 35,000 test $5 multiplied by 8 50 customer supports always. And this is too nice. 7 15 Yeah. And then we have savings. A transportation costs of for parts and then 3 50 Multiply by 2-5 fewer loads. And this is 17 8,007, 15 And the 7th A one C repair costs. So And this is 89. The terrorism is supplied by 8000. We play ours And this is 712,000. Under the opportunity costs. It's one night, 2 6 500. And the contribution imagine for me three steals And this is 1,680,000. And then they cost savings. An additional contribution margin 33606 500. So this is what's going to be now because the expected relevant benefits of 363 million 606,500 exceeds the expected relevant cost of a new component. So you expected ready once benefits is 2060 or 6 500. This exceeds the expected really want costs Which is one million To 60,000. Right? So this big prints should introduce the new components and you should know that the opportunity cost benefits in the form of higher contribution majene from increased is an important component for just to find the investment in the new components. So that's the answer. Not the second question says Suppose that the estimates of 140, I'm sorry Suppose that the estimates of 140 additional printing search purses. So this uncertain what is the minimum number of additional printing presses does pick brains needs to sell to justify adopting the new components. So for this, the incremental cost of the new components is one million to 60 1000 and is less than the incubator savings. And we work with the costs. And this is the cost to 1,096,500. And this is as a result of 1,000,001 06 1000 plus 29007 50 Plus 78,007, 15 Lost 7, 7 months, 2000. So then this is beneficial for speak, print to invest in the new components even without making any seals. So it is beneficial for spring greens. So invests mm didn't you compliments without making additional series. So that's the answer?
