Question

Sung is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.

Answer 1

Answer:

Step-by-step explanation:

Use the equation

89 < 75 + 0.7*M                Subtract 75 from both sides

89 - 75 < 0.7M                  Combine

14 < 0.7 M                          Divide both sides by 0.7

14/0.7 < M

20 < M

If M goes over 20 then the flat rate is cheaper.
