Question

John bought three cars in the last year for a total of $30,000 he paid the same amount for each of the first two cars and got the third one for twice the amount of the first car which equation can be used to find out how much John paid for each car? Ignore sales tax

1.x(30,000)=2x
2.x + 2x=30,000
3.30,000x=x+2x
4.x+x+2x=30,000

Answer 1

The answer is 4. Let’s say x is equal to 7.5. The price of the first 2 cars were they same price and that price being x. Therefore the third car price is double the first meaning it is 2x. The last equation shows a proper mathematical equation.

Answer 2

the 4th answer would be the best equation to find out how much John paid for each car
