Question

A recylcying center was offering cash for different types of recylcables. For each pound of copper they paid $1.48. For each pound of aluminum they paid $1.55. And for each pound of plasic they paid $0.30. Jesse took in 50 pounds of copper, 15 pounds of aluminum, and 10 pounds of plastic. How mush money was he paid for his recyclables?

Answer 1

$100.25

Explanation:

To figure this out we can write a really simple equation! to start we're going to identify our variables: in this case we'll make
`T` for total,
`c` for the amount of copper,
`a` for the amount of aluminum, and
`p` for the amount of plastic. We can then create this equation to represent the sum of the amount of material times the value. This equation will look like this:
`T=1.48c+1.55a +.30p`

Now that we have an equation written out, we can plug in the amount of each material to get
`T=1.48(50)+1.55(15)+.30(10)`. We can then simplify this by following PEDMAS and multiplying to get
`T=74+23.25+3` and then all we have left is to add to get
`T=100.25`
