Your computersupply store sells two types of inkjet printers. The first, type A, costs $237 and you make a $22 profit on each one. The second, type B, costs $122 and you make a $19 profit on each one. You can order no more than 120 printers this month, and you need to make at least $2,400 profit on them. If you must order at least one of each type of printer, how many of each type of printer should you order if you want to minimize your cost? Possible answers:
69 of type A : 51 of type B
40 of type A : 80 of type B
51 of type A : 69 of type B
80 of type A : 40 of type B

2.A factory can produce two products, x and y, with a profit approximated by P = 14x + 22y – 900. The production of y can exceed x by no more than 200 units. Moreover, production levels are limited by the formula x + 2y ≤ 1600. What production levels yield maximum profit? x = 400; y = 600 x = 0; y = 0 x = 1,600; y = 0 x = 0; y = 200

If we let: a = number of type A computers b = number of type B computers Then we can produce the following equations: Amount of Computers a + b ≤ 120 Cost of Computers: C(a,b) = 237a + 122b Profit from computers: 22a + 19b ≥ 2400

So hmm, would it be 40 of type A and 80 of B ? x.x I'm just sorta guessing here

HeroBest ResponseYou've already chosen the best response.3
So now we take the amount equation and the profit equation and solve for a and b: a + b ≤ 120 22a + 19b ≥ 2400 Multiply the first equation by 22 to get: 22a + 22b ≤ 2640 22a + 19b ≥ 2400 Isolate 22a in both equations: 22a ≤ 2640  22b 22a ≥ 2400  19b Now set: 22a ≤ 22a 2400  19b ≤ 2640  22b Place like terms on the same side: 22b  19b ≤ 2640  2400 3b ≤ 240 b ≤ 240/3 b ≤ 80 Thus a ≤ 40 since we know that a + b ≤ 120

I think you did some plug and play to figure it out. You already had answer choices.

I, on the other hand, figured it out the hard way. It was very toilsome.

Believe it or not, what I posted IS the easy way. Good luck finding an easier way.

oh goodness... haha yeh I guess, so how shall I go about this second question?

HeroBest ResponseYou've already chosen the best response.3
Well from looking at the answers, it will be either A or D. And if I had to guess, I would guess A

HeroBest ResponseYou've already chosen the best response.3
Matter of fact, I'm just going to say the answer is A

Graph the system of constraints and find the value of x and y that maximize the objective function. Objective function: C = 7x – 3y (2.5, 2.5) (0, 2) (0, 0) (5, 0)

Any ideas on this one? It's the last one I have no idea about :/ ?

HeroBest ResponseYou've already chosen the best response.3
Well basically we have to find the coordinates the yield the maximum value of C. This is an easy one too.

All you have to do is just plug the values into the formula

c'mon Megan, think outside the box. Which set of coordinates can you plug into the function to yield the highest value of C?
