To find Chico's cost per mile to operate his car, we need to calculate his total cost and then divide it by the total number of miles he drove.
Total cost = Variable costs + Fixed costs - Present value
Total cost = $1,908.00 + $800.00 - $8,652.00
Total cost = $1,908.00 + $800.00 - $8,652.00
Total cost = $2,708.00 - $8,652.00
Total cost = -$5,944.00
Since the total cost is negative, it indicates that Chico has gained $5,944.00 in value from operating his car.
Now, we can find the cost per mile:
Cost per mile = Total cost / Miles driven
Cost per mile = -$5,944.00 / 13,890 miles
Cost per mile ≈ -$0.427 per mile
