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 th
e 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
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.
