he surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month? Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra. The instructor makes $ a month.

$472

Explanation:

• First, find how much the instructor receives a month from Sandra.

Step 1 - Insert the number of hours of lessons the instructor gives to Sandra in one month

y = 8x + 12

y = 8(32) + 12

Step 2 - Simplify by multiplying eight by thirty two

y = 8(32) + 12

y = 256 + 12

Step 3 - Add

y = 256 + 12

y = 268

Therefore, the instructor receives $268 from Sandra a month.

• Next, find how much the instructor receives a month from Bella.

Step 1 - Insert the number of hours of lessons the instructor gives to Bella in one month

y = 8x + 12

y = 8(24) + 12

Step 2 - Simplify by multiplying eight by twenty four

y = 8(24) + 12

y = 192 + 12

Step 3 - Add

y = 192 + 12

y = 204

Therefore, the instructor receives $204 from Bella a month.

• Finally, add both amounts together

268 + 204

472

Therefore, the instructor makes $472 a month.
