Explanation:

Step1: Calculate Riley's cost per car

To find the cost per car washed for Riley, divide the total resource - use by the number of cars washed. The formula is $\text{Cost per car}=\frac{\text{Total resource use}}{\text{Number of cars washed}}$. For Riley, the total resource use is $\$18$ and the number of cars washed is $6$. So, $\frac{18}{6}=3$.

Step2: Calculate Sean's cost per car

For Sean, the total resource use is $\$48$ and the number of cars washed is $12$. Using the same formula $\text{Cost per car}=\frac{\text{Total resource use}}{\text{Number of cars washed}}$, we have $\frac{48}{12}=4$.

Step3: Calculate Jake's cost per car

For Jake, the total resource use is $\$64$ and the number of cars washed is $8$. Using the formula $\text{Cost per car}=\frac{\text{Total resource use}}{\text{Number of cars washed}}$, we get $\frac{64}{8}=8$.

Answer:

Riley spent $\$3$ on resources per car washed.
Sean spent $\$4$ on resources per car washed.
Jake spent $\$8$ on resources per car washed.
