Question

$105 for 12/1/2 hours Part A Find the unit rate.

Answer 1

The fee is $105 for 12.5 hours, then to find the unit rate we do the quotient:

105 / 12.5 = $8.4 per hour.

Now Part B:

Then, for 40 hours, we simply multiply $8.4 times 40 and get: $336.

So the cost will be $336 per 40 hours.

Please notice that I typed 8.4 (eight POINT four) not 8/4.

if they want it in fraction form you should type: 42/5

Did you complete part B as well?
