Your computer supply store sells two types of inkjet printers. The first, type A, costs $241 and you make a $25 profit on each one. The second, type B, costs $103 and you make an $11 profit on each one. You can order no more than 140 printers this month, and you need to make at least $2660 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?

Ответ:
The number of printers for type A = x = 80 printers
The number of printers for type B = y = 60 printers
Step-by-step explanation:
Let the number of printers for type A = x
Let the number of printers for type B = y
You can order no more than 140 printers this month
x + y ≤ 140
x + y = 140
x = 140 - y
Profit for type A = $25
Profit for type B = $11
You need to make at least $2660 profit
25x + 11y ≥ 2660
25x + 11y = 2660
Substitute 140 - y = x
25(140 - y ) + 11y = 2660
3500 - 25y + 11y = 2660
3500 - 2660 = 25y - 11y
840 = 14y
y = 840/14
y = 60 printers
x = 140 - y
x = 140 - 60
x = 80 printers
To minimize cost :
The number of printers for type A = x = 80 printers
The number of printers for type B = y = 60 printers
