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

Answer 1

Let's denote the number of hours spent teaching lessons as "h".

The total amount of money earned from the swimming lessons can be expressed as: 8h.

The total amount of money earned from the registration fees is $20.

We are told that the total amount earned for the day is $52.

Therefore, the equation to solve is:
8h + 20 = 52

To solve for h, we need to isolate the variable. Let's begin by subtracting 20 from both sides:
8h = 52 - 20
8h = 32

Next, we divide both sides of the equation by 8:
h = 32 / 8
h = 4

Therefore, you spent 4 hours teaching swimming lessons.
