Question

A pre-paid cell phone plan has a flat rate of $15 with an additional cost of $0.15 per

minute. At most, how many minutes can Chelsea purchase if she has $35?
Write an inequality for this statement, write out 3 values that would make the inequality true

Answer 1

anything less than 133 would be true

Explanation:

35 ≥ 0.15m + 15

solve for m

subtract 15 from both sides

20 ≥ 0.15m

divide both sides by 0.15

133.33 ≥ m

m cannot be more than 133 minutes
