The tennis club where you play tennis charges $50.00 per month and $10.00 per hour of court time. If your current month's bill is $100.00, how many hours of court time did you use

5 hours

Explanation:

Data provided in the question

Per month tennis charges = $50

Court time per hour = $10

Current month bill = $100

By considering the above information we can find out the variable expense that is shown below:

= Current month bill - per month tennis charges

= $100 - $50

= $50

So, the number of court time hours usage is

= $50 : $10

= 5 hours
