Question

2. Your computer-supply 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? (1 point)
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

Answer 1

do you just wnat the answer or do you want to learn the material?

Answer 2

both

Answer 3

Please!

Answer 4

okay can you write down an equation that describes how much profit you make, based on the number of printers A and B you buy?

Answer 5

I really have no clue

Answer 6

c(x,y) = 237x + 122y
p(x,y) = 22x + 19y ≥ 2400
x + y ≤ 120

22x + 19y ≥ 2400
x + y ≤ 120

22x + 19y ≥ 2400
19x + 19y ≤ 2280

Answer 7

thank you :)

Answer 8

19y ≥ 2400 - 22x
19y ≤ 2280 - 19x

19y ≥ 19y
2400 - 22x ≥ 2280 - 19x
2400 - 2280 ≥ 22x - 19x
120 ≥ 3x
120/3 ≥ x


40 ≥ x
80 ≥ y

Answer 9

so
x = 40
y = 80

Answer 10

@Hero can you help me with another?

Answer 11

Another one just like this? I showed you all the steps.

Answer 12

No, a different one.

Answer 13

@KushanaBrown, the way things work here is, once you get help with a question, you close the question. After doing that, If you have another question, then you post a new question in the ask a question box.
