Question

The instruction booklet for a CD player says that the player uses about 0.2 kilowatt of electricity per hour. If electricity costs $0.30 per kilowatt hour, how much does it cost to run the player for an hour?

Answer 1

Hello!

ANSWER:

The boxes weigh 112.5 lb altogether.

EXPLANATION:

Each box weighs 7.5 lb. We want to find out how much 15 boxes would weigh.

Multiply the weight of each box (7.5 lb) by the amount of boxes (15):

7.5 × 15 = 112.5
