Question

Cameron bought two used cars and fixed them

Answer 1

Using a system of equations, it is found that the selling price of each car was:

• First car: $3,400.

• Second car: $7,400.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given by:

• Variable x: Selling price of the first car.

• Variable y: Selling price of the second car.

Considering the total profits, and the profit of each car, we have that:

0.4x + 0.35y = 3950.

Cameron paid for the first car was $4,000 less than the price for the second car, hence:

x = y - 4000.

Hence, replacing in the first equation:

0.4(y - 4000) + 0.35y = 3950.

0.75y = 5550

y = 5550/0.75

y = $7,400

x = 7400 - 4000 = $3,400.

Then, the selling prices are given as follows:

• First car: $3,400.

• Second car: $7,400.
