A rental car agency charges $200.00 per week plus $0.15 per mile to rent a car. How many miles can you travel in one week for $288.50?

590 miles

Step-by-step explanation:

let's set it up

200=base

0.15 is our variable

and total is 288.50

200+0.15x=288.5

subtract 200 from both sides

0.15x=88.5

divide 0.15 from both sides

x=590

we can plug it in to double check our work

200+0.15(590)=288.50
