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?

You taught for 4 hours

Step-by-step explanation:

52-20=32 how many hours you spent teaching

then divide that by eight which is 4 so youve been teaching for 4 hours

You taught for 4 hours

Step-by-step explanation:

Let this number of hours be x. Then:

Total earned = $20 + ($8/hr) x

Equate this to $52 and then solve the resulting equation for x:

20 + 8x = 52

Then 8x = 32, and x = 4. You taught for 4 hours.
