Question

The recycling center pays $0.25 per pound for aluminum and $0.11 per pound for glass. David received $5.75 for his aluminum cans and $2.53 for his glass bottles How many pounds of glass and aluminum did he recycle? (Hint: Change dollars to cents first.)

Answer 1

He recycles 23 pounds of glass and 23 pounds of aluminum.

Step-by-step explanation:

To know the number of pounds of glass, we need to divide the amount received for his glass bottles by the amount per pound of glass, so:

`(2.53)/(0.11)=23\text{ pounds of glass}`

In the same way, to know the number of pounds of aluminum, we need to divide the amount received by the amount per pound, so:

`(5.75)/(0.25)=23\text{ pounds of aluminum}`

Therefore, he recycles 23 pounds of glass and 23 pounds of aluminum
