Question

Erin is a dog groomer. She charges a $6.00 base fee plus an extra $0.50 per pound. If x represents the weight of the dog in pounds, which equation models her income for each dog groomed?

Income = 0.5 x + 6
Income = 5 x + 6
Income = 6 x + 0.5
Income = 6 x + 5

Answer 1

the first equation

Explanation:

The 6 is the same amount no matter the weight of the dog. .5x represents 50 for each pound.

If a dog weight 20 pounds, it would cost 6 + .5(20)

If a dog weight 30 points it would cost 6 + .5(30) and so on.

Answer 2

Income = 0.5x + 6

0.5 represents how much each pound costs. For example, If the dog was 10 pounds:
0.5(10) + 6
5 + 6
= $11 total
