name: ____ date: __ hr: ____

Explanation:

Let's solve problem 1:

Step1: Identify the formula for rate

To find the money made per hour (unit rate), we use the formula: Rate = Total Money / Total Hours.
Here, total money is $93.50 and total hours is 11.

Step2: Calculate the rate

Substitute the values into the formula: $\frac{93.50}{11}$
$93.50\div11 = 8.5$

Answer:

You make $8.50 per hour.
