Exercise 1 Page 164

To find our hourly wage, we need to divide the

total

earnings

by the number of

hours

we

worked .

Hourly wage = \frac{Total earnings}{Hours worked}

Let's use this equation and the fact that we earned

$ 352.50

by working for

37 \frac{1}{2}

hours.

Hourly wage = \frac{3 5 2 . 5 0}{3 7 \frac{1}{2}}

Write as a decimal

Hourly wage = \frac{3 5 2 . 5 0}{3 7 . 5}

Use a calculator

Hourly wage = 9.40

The hourly wage is

$ 9.40 .
