john is doing a fundraiser for school. he needs to sell at least $200 worth of items. shirts cost $10 each and hats cost $8 each. he must sell more than 12 hats.

Answer 1

200 = 10s + 8h

Let h be > 12

Let h be 13

200 = 10s + 13(8)

200 = 10s + 104

This won't be evenly divisible by 10

200 = 10s + (14)(8) nope...

200 = 10s + 15(8)

200 = 10s + 120

80 = 10s

s = 8 shirts and h = 15 hats
