Question

Read the following description of a relationship:

Emmet helps to organize road races. He sets out 68 cups of water at each rest
stop and 100 more cups of water at the finish line.
Let r represent the number of rest stops and b represent the total number of
cups of water.
Find the value of b when r = 9.
b = ?

Answer 1

b = 712 cups of water

Explanation:

First, you have to multiply 68 by 9. This is because there are 68 cups at each rest stop, and there are 9 rest stops. We are finding the total number of cups of water at all the rest stops.

68 • 9 = 612

There are 100 cups of water at the finish line, so add 612 and 100.

612 + 100 = 712

Therefore, there are 712 cups of water.
