Answer:
8 Miles
Step-by-step explanation:
Start by creating an equation based off what you know. To start we know it costs $3 just to get a ride + $2 for ever mile we travel (represent this using x)+ the $1 tip we left=$20.
3+2x+1=20
Now you add the like terms together(3+1)
2x+4=20 Subtract the 4 from both sides.
-4 -4
2x=16 Now you just divide each side by 2
_ _
2 2
x=8
Don't forget your label (miles)
