Answer 1

15x>200.  The minimum number of hours he must work to earn at least $200 is 14 hours.  Working 14 hours will allow him to receive $210.  This is the minimum number of hours he can work because if he works 13 hours instead, he will only make $195, which is less than 200.  15x>200 (15x is equal to or greater than 200) x=14.

Answer 2

Just divide 200 by 15 and you’ll get 13.3333 so you just add one and get 14
