Question

Megan has a dog-sitting business. She charges an initial fee of $10 to watch the dog, plus an hourly fee of $4.

Megan watches Frenchie the bulldog for m hours. She wants to make at least $50. Write an inequality for the number of hours, m, that Megan needs to watch Frenchie for to meet her goal.

Answer 1

Below

Explanation:

Standard charge = $ 10

plus hourly charge 4 m where 'm = hours

10 + 4m needs to be at LEAST $ 50

10 + 4m ≥ 50 which can be re=arranged Subtract 10 from both sides

4m ≥ 40 now you can divide both sides by 4

m ≥ 10 hours
