Final answer:
The amount Mark will be financing for the car is $16,920.
Step-by-step explanation:
To calculate how much Mark will be financing for the car, we need to find the amount of the down payment first. A 10% down payment on an $18,800 car is 0.10 x $18,800 = $1880.
To find the amount Mark will be financing, we subtract the down payment from the total price of the car. $18,800 - $1880 = $16,920.
Therefore, Mark will be financing $16,920 for the car.
