Question 911557: Joaquin buys 3 packs of light bulbs.each pack contains 12 light bulbs.after changing the bulbs in his house,he has 15 bulbs left.How many light bulbs did he use? Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! In 3 packs of light bulbs, with each pack containing 12 light bulbs, Joaquín had light bulbs.
If Joaquín used as many bulbs as he needed to change all the bulbs in his house, and he has 15 bulbs left,
then he used bulbs.
If an equation was needed, we could say = number of bulbs Joaquín used. So, ---> ---> ---> .
