Question

Raheel is comparing the cost of two parking garages. Garage A charges a flat fee of $6 per car plus $0.50 per hour. Garage B charges a flat fee of $2 per car plus $1 per hour.

Answer 1

#A

• Flat fee=6
• Rate of change=0.5

Equation in slope intercept form

• y=mx+b
• y=0.5x+6

#B

• Flat fee=2$
• Rate of change=1

Equation in slope intercept form

• y=x+2

Now for compare take any no

Let's take 10

For garage A

• y=0.5(10)+6=5+6=11$

For garage B

• y=10+2=12$

Hence Garage B is charging more

Answer 2

$6 + .50x = $2 + $1.00x

4 = .50x

8hr = x, the number of hours when both garages cost the same amount

$6 + .50 x 8 =

$10 would be the cost a both garages after 8 hours
