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!)
