Charles can earn $15 per hour when he housesits and $22 per hour when he walks a dog. If he housesits for 10 hours and walks 3 dogs, how many dollars will Charles earn?
Thoughts? Step-by-step reasoning:
Housesitting = 15 * 10 = 150. Dog walking = 22 * 3 = 66. Total earned is 150 + 66 = $216.
Thus, the answer is 216.
