Question

A moving company charges a flat rate of $180, and an additional $6 for each box. If a taxi service would charge $15 for each box, what is the minimum number of boxes you would need for it to be cheaper to use the moving company?

Answer 1

20

Explanation:

The expression that best represents the total cost of shipping boxes through the moving company is 180+6b.

The expression that best represents the total cost of shipping boxes through a taxi service is 15b.

The expression that best represents where the cost of shipping through the moving company is less than using the taxi is 180+6b≤15b.

Solving this inequality for b, we get b≥20.
