4) When you buy a new car, you will often make a down payment and also take out a loan. The cost of a
new car is the loan amount added to the down payment.
a) Write an equation that represents this information. Use L for loan amount, D for down
payment, and C for cost of the car.
b) Use your equation from part a to find the down payment if the loan amount is $8000 and the
cost of the car is $10,500. To earn full credit, you must show that you used your equation
from part a and you must show how you solved the equation.
