Question

The distance of a trip

An airport offers free parking for 30 minutes and then charges $2.00
for each hour after that. How is the price for parking related to the
total time a car is parked?

write an equation for each relationship

Answer 1

T-.5 = x (200)

Explanation:

Let T = total time in hours

30 mn = .5 hours 30 /60 = .5

$ 2.00 is the rate per hour.

so T − .5 = the time that will be charged at the rate

Therefore the total charge is then

T − .5 × 2.00
