Answer:
10
Step-by-step explanation:
one pencil costs 2.50.
letting x = the number of pencils, your inequality would be:
2.50 * x <= 27
solve for x to get x <= 27/2.50 = 10.8
if you buy 10 pencils, the cost is 10 * 2.50 = 25.
if you buy 11 pencils, the cost is 11 * 2.50 = 27.50
your answer would be x = 10
