Answer 1

Answer:

The total amount the instructor makes in a month is $268+204 = 472$ dolars.

Step-by-step explanation:

We need to sum the total cost paid by Sandra and by Bela. As you said, we can get it from the equation $y = 8x+12$, where $x$ stands for the number of hours.

The amount of money paid by Sandra is $y = 8\cdot 32+12 = 268$ dolars.

The amount of money paid by Bela is $y = 8\cdot 24+12 = 204$ dolars.

So the instructor makes $268+204 = 472$ dolars a month.
