Question

During summer vacation you charge people $8 per hour for swimming lessons and $20 registration fee. If you make $52 one day, how many hours did you spend teaching lessons? Algebra

Answer 1

4 hrs

Explanation:

Let h be the number of hours spent teaching lessons

Then 8h is the amount earned from swimming lessons

Total amount earned = amount from swimming lessons + $20 registration fee

Total amount earned = $52

Therefore, 52=8h+20

32=8h

h=4 hrs (Answer)
