To find out how many pounds of apples Bill can buy, we can set up an equation based on the information given.
Let \( x \) represent the number of pounds of apples Bill can buy. The cost per pound is $1.25, and he has a total of $5 to spend.
The equation can be set up as follows:
\[ 1.25x = 5 \]
Now, you can solve for \( x \) to determine how many pounds of apples Bill can buy.
