Peter went to the hardware store with $10. He needs to purchase some light plate and outlet covers. Here are the prices at the store:
Light plate covers: $0.75
Outlet plate covers: $1.25
He has enough money to purchase which set of item below?
A. 7 light plate covers and 4 outlet plate covers
B. 6 light plate covers and 6 outlet plate covers
C. 6 light plate covers and 4 outlet plate covers
D. 5 light plate covers and 6 outlet plate covers
C. 6 light plate covers and 4 outlet plate covers
Explanation: You need to find the total cost of each group of items by setting numerical expression. The group that totals less that $10 is what he can afford.
The numerical expressions of each group would look like this:
7(.75) + 4(1.25) = $10.25
6(.75) + 6(1.25) = $12
6(.75) + 4(1.25) = $9.50
5(.75) + 6(1.25) = 11.25
Because C is less than $10, that is the correct answer.
