Question

Melanie charges $4.50 per hour when she washes cars, plus $5.00 for supplies. Which function rule represents the amount y Melanie charges to wash cars for x hours?

a. y=0.50x
b. y=4.50x+5.00
c. y=5.00x+4.50
d. y=9.50x

Answer 1

4.50 since it has to do with rate:
y = 4.50x
Then find the automatic cost: 5
y = 4.50x + 5.00

B!
