Question

Sara just bought a new car. This car cost $33,646.66 less than twice the price of her first car. How much did the first car cost, if she paid 1,070.78 dollars for her new car?

Answer 1

USD 17,358.72.

Step-by-step explanation:

Hello,

In this case, for this math problem, we can write:

2x - 1,070.78 = 33,646.66

Whereas x represents the value of her old car, thus, we obtain:

2x = 33,646.66 + 1,070.78

x = 34717.44 / 2

x = 17,358.72

It means that her first car costed USD 17,358.72.

Best regards.
