Problema Solution

The monthly parking fee at the

Safety First Parking Garage is one and one-half times

last year’s monthly fee, but compact cars will now

receive a $10 per month discount. If the owner of a

compact car pays $98 per month this year, what was

his monthly fee last year?

Answer provided by our tutors

x = old fee

y = new fee

 

y = 1.5x

 

y - 10 = 98

y = 108

 

=>  1.5x = 108

 

x = 72

 

His monthly fee last year was $72.
