Question

Plan 1 charges $3 per walk plus $10 for groming. Plan 2 charges $5 per walk and free grooming. What equation would be the number of walks when the two plans cost the same amount?

Answer 1

Answer: The two plans would cost the same amount when they each did 5 walks. (answer is 5)

Step-by-step explanation:

plan one is y=3x+10 and plan two is y=5x

5x=3x+10 subtract 3x from each side

2x=10 divide 10 by 2 to get x alone

x=5

(check of work)

y=3(5)+10

y=25

y=5(5)

y=25
