Question

The base parking at a mall on a Sunday is $2 per hour. If a vehicle is parked for 4 hours, only $6 is charged. What percentage is saved on the base charge for a vehicle parked for 4 hours?

Answer 1

4 hours parking at $2/hr = 4 x 2 = $8

4 hours special charge = $6

Discount = $8 - $6 = $2

Percentage discount = 2/8 x 100 = 25%

Answer: 25% (Option C)

Answer 2

$2=1 hour
$8=4 hours
She paid $6, so the amount save $8-$6=$2
2/8×100=25%
