Answer 1

Answer:

  19 miles

Step-by-step explanation:

Let m represent the number of miles traveled. Then the delivery charge is ...

  charge = $5.00 + $0.15·m

You want to find the value of m that makes the charge by $7.85, so you want the solution to ...

  $7.85 = $5.00 +$0.15·m

  $2.85 = $0.15·m . . . . . . . . . subtract $5 (this gives the mileage charge)

  $2.85/$0.15 = m = 19 . . . . . divide by the coefficient of m

The number of miles traveled is 19.
