Question

A contractor charges $84 per half hour to install roofing. How much do they
charge per hour?

Answer 1

To determine how much the contractor charges per hour, we need to convert the price per half hour to the price per hour.

The price per half hour is $84.

To convert this to the price per hour, we can use the following formula:

Price per hour = (Price per half hour) x 2

Using this formula, we get:

Price per hour = $84 x 2
Price per hour = $168

Therefore, the contractor charges $168 per hour to install roofing.

Answer 2

Answer:$168 per hour

Step-by-step explanation: so in a half hour they charge $84 .

a half hour is 30 minutes and you need another half hour so double $84

$84x2=168
