Let x = number of miles driven
Total cost = Weekly cost + mileage cost
Total cost = Weekly cost + (mileage rate)(number of miles driven)
Plugging in values
374 = 230 + 0.15x Subtract 230 from both sides of the equation
374-230 = 230 + 0.15x - 230 Simplify
144 = 0.15x divide both sides of the equation by 0.15
144/0.15 = 0.15x/0.15 Simplify
960 miles = x
