To raise funds for uniforms and travel expenses, the soccer team is holding a car wash in a part of town with a lot of car and truck traffic. The team spent $90 on supplies like sponges and soap. They plan to charge $10 per car and $20 per truck. Their goal is to raise $460. How many cars do they have to wash if they washed the following numbers of trucks? 27 trucks

1 car

Step-by-step explanation:

20 x 27 = 540

if they earn $540 from 27 trucks but spent $90 on supplies then they really only have $450 towards their goal of $460;

they need another $10 which means they must wash one car

the solution is the point
