Answer 1

A car rental company offers two plans for renting a car:

Plan A: 30 dollars per day and 17 cents per mile

Plan B: 50 dollars per day with free unlimited mileage

Plan A

y = 30 +0.17* n

n= number of miles run

Plan B

y= 50

Plug in y = 50

50 = 30 +0.17 n

0.17 n= 20

n= 20/0.17

= 2000/17

so up to 117 miles Plan B will save money per day

Answer 2

30+.17x=50

.17x=20

x=117.65miles

A better price for "b" is after117.65miles.
