Question

Grace needs $45 to go to Six Flags. She has $13. She earns $8 an hour walking dogs. Which
equation represents how many hours Grace will have to walk dogs to earn enough money to go
to Six Flags? *

Answer 1

Answer: C. 13 + 8x = 45

Step-by-step explanation:

She already has 13 dollars. This would be the b-value in the equation, thus eliminating options A and B because those two feature 13 as the m value.

She earns $8 per hour. Let x = number of hours walking dogs.

Since 8 is the slope, it would be attached to x, thus either C or D would be the correct response

Since Grace is adding 8 dollars per hour, not subtracting, D is incorrect, leaving C to be the correct answer.
