Answer 1

1. Caitlyn is going away to college and will need to rent a truck to help

move. The cost of the truck is $35 plus $0.79 per mile. If her college

is 85 miles away and she budgeted $100 for the rental, will she have

enough money?

we know that

The equation in slope intercept form of this situation is

y=mx+b

where

m=$0.79 per mile

b=$35

y -----> is the total cost

x -----> the number of miles

so

y=0.79x+35

so

For x=85 miles

substitute

y=0.79(85)=35

y=$102.15

we have that

102.15 > 100

therefore

she not have enough money
