To find out how many cans are needed to make 1 pound of aluminum, we can start with the information that 8 empty cans produce 1/4 pound of aluminum.
To find the number of cans per pound, we can set up a calculation as follows:
- Since 8 cans produce 1/4 pound, we want to find out how many cans will produce 1 pound: \[ \text{Cans per pound} = \text{Cans for } \frac{1}{4} \text{ pound} \times 4 \] \[ \text{Cans per pound} = 8 \text{ cans} \times 4 = 32 \text{ cans} \]
So, it takes 32 cans to make 1 pound of aluminum.
Therefore, the answer is:
__ 32 can(s) per pound of aluminum
