F(x+6) +2 up and right in a graph is positive
1. move 78.2 over to the over side. This will give you 287-78.2.
2. when you have .5x = 208.8, divide both sides by .5
3. this should give you x= 417.6
4. make sure to check your work by plugging you answer back into x.
ANSWER : Rozalie spent 6.73 hours at the garage
rate of change = $2.75
base fee = $7.50
set up your equation:
2.75h + 7.5 = 26
($2.75/hour plus the base fee of $7.50 equals the total amount spent, $26)
Now just solve for h
2.75h + 7.5 = 26
2.75h = 18.5
h = 6.727273 (rounded)
h = 6.73
So the answer would be Rozalie spent about 6.73 hours at the garage.
