At a school fund-raising drive, $350 was collected for washing sedans, coupes, and sport -utility vehicles . The cost of a wash for any type of vehicle was $2. Twice as many coupes were washed as sedans . Four times as many sport - utility vehicles were washed as sedans. How many coupes were washed?

So we can say that sedans are x, as the other two cars are based on it.

So there are 2 times as many coupes as sedans so coupes are 2x. And there are 4 times as many sports utility vehicles than sedans so they are 4x.

So we can add them all together to get the number of cars washed.

The equation is: x+2x+4x=350
Simplifying your get 7x=350, and x becomes 50.

We then divide 50/2 because 1 car is equal to $2. So then there would be 50 coupes (2 * 25 or 2x) that were washed.

25 sedans, 50 coupes, and 100 sports-utility vehicles were washed.

I hope this helps! (Please thank or brainliest if you can, I’d really appreciate it!)
