Question

A riding stable charges $150 per month to board a horse plus $6.75 per bale of hay that the horse eats. What is the maximum number of hay bales that Shiloh eats in a month if his monthly boarding cost is at least $225.00 and at most $255.00? Round your answer to the nearest whole bale that satisfies the inequality.

A 12 bales
B 11 bales
C 16 bales
D 15 bales

Answer 1

225 < = 150 + 6.75b < = 250
225 - 150 < = 150 - 150 + 6.75b < = 250 - 150
75 < = 6.75b < = 100
75 / 6.75 < = 6.75/6.75b < = 100/6.75
11.11 < = b < = 14.81

the only answer choice that works is 12 bales
