Okay. 

You want to take all the information and basically put it all together. So each car spark plug costs $0.75$ and there are $8$ of those. Also, each truck spark plug costs $3.00$ and there are $4$ of those. So you want to solve this: $(0.75*8)+(3.00*4)=$

When you do that you should get: $18$
