Parking lots A and B each charge a set fee for parking plus an hourly rate. Hours Parked48Lot A Cost ($)19.00/33.00

Lot B Cost ($)20.00/32.00

How many more dollars does it cost per hour to park in Lot A than in Lot B? Give the answer as a decimal showing dollars and cents.

$0.5

Step-by-step explanation:

Given :

Hours ___Lot A Cost ($) ___ Lot B Cost ($) 419.00 20.00

8 33.00 32.00

Using the equation :

y = mx + C

m = slope = Hourly charge

C = intercept = set park fee

m = y2 - y1 / x2 - x1

For LotA:

m1 = (33 - 19) / (8 - 4)

m1 = 14 / 4

m1 = 3.5

For LotB:

m2 = (32 - 20) / (8 - 4)

m2 = 12 / 4

m2 = 3

Since, m is the hourly cost :

Difference = m1 - m2

= 3.5 - 3

= $0. 5
