Question

The smith family rented an RV for a 7-day vacation. The cost to rent the RV was $80 per day plus $0.50 per mile. How many miles were driven if the total cost was $1355?

Answer 1

day = d

miles = m

 

80(d) + 0.50(m) = total cost

 

7 day vacation is d = 7

 

80(7) + 0.50(m) = 1355

560  + 0.50(m) = 1355

-560                    -560

0.50(m) = 795

divide 0.5 from both sides

m = 1590 miles
