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? A. 2 hoursB. 5 hoursC. 10 hoursD. 8 hours

Option B. 5 hours

Step-by-step explanation:

The tennis club charges monthly fees = $50.00

and per hour charges of court time = $10.00

Lets assume you play number of hours in a month = x hr

So, per hour charges would be = $10x

Total payment = monthly charges + charges of played hours

$100.00 = $50.00 + 10x

10x = 100 - 50

10x = 50

x = 5

Option B. You used 5 hours court time.
