The base parking charge 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? A 10%
B 20%
C 25%
D 30%
E 50%

Respuesta :

2 dollars = 1 hour
8 dollars = 4 hours
she paid 6 dollars so the amount saved = 8-6 = 2 dollars
percentage saved =  × 100
percentage saved = 25%

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)
