Answer:
The new car costs more
Old car = $5062.125
New car = $7161.357
Step-by-step explanation:
Manny drives an average of 110 miles per week with his old car. The old car gets 16 miles per gallon. The cost per gallon is $2.65 repair and Maintainance costs an average of $740 per year. 
For the old car, to find the amount spent on the car we have 
110/16 * 2.65 = $18.21875 / week
There are 52 weeks in a year. We have 
10.21875*52 = $ 947.375
947.375 + 740
= $1687.375
= 1687.357 * 3
= $5062.125
The new car cost $6500 over a three year loan process. 
The car gets 28 miles per gallon. It requires a maintenance f $10 per month. For the new car to find the amount, we have 
110*28 * 2.65 *52 = $541.357
541.357 + 10(12) + 6500
= $7161.357
