Tri City sells four times as many dishwashers as Solly Company. The difference between their sales is 96 dishwashers. How many dishwashers did Tri City sell?
We use a system of equations to solve this. Since tri city sells 4 times it becomes 4x and solly company is x. Then we do 4x-x=96. 3x=96. x=32. We are not finished yet. We still have to multiply x by 4. x=128. Tri City sold 128 dishwashers.
