Question

You need to buy some shirts and pants for

school. Pants cost $20 each and shirts cost
$15 each. You have $120, and need to buy at
least 9 items.

Answer 1

x=pants
y=shirts

20x+15y ≤120
You can buy 2 pants, 2•20=40; you can buy 5 shirts, 15•5=75.
40+75=115
115 ≤120
You could buy
1 pair of pants and 6 shirts, 20+90=110
