Answer:
The answer is $18.
Step-by-step explanation:
The distributive property of multiplication is :
[tex]a(b+c)=a\times b+a\times c[/tex]
Given is:
8 car spark plugs cost $0.75 a piece and 4 truck spark plugs cost $3.00 a piece.
So, we can find the total cost as:
[tex](8\times0.75)+(4\times3)[/tex]
[tex]6+12[/tex] =18
So, the answer is $18.
