Answer:
pounds of blueberries he need to buy more.
Explanation:
Given:
Horace buys 2 ¾ pounds of blueberries for a pie.
He needs 48 ounces of blueberries for the pie.
Now, to find pounds of blueberries he need to buy more.
Number of pounds Horace buys blueberries for the pie = 2 ¾ pounds.
He needs blueberries for the pie = 48 ounces.
Now, by using conversion factor convert ounces into pounds:
1 ounce = 0.0625 pounds.
48 ounces = 0.0625 × 48 pounds.
48 ounces = 3 pounds.
Horace needs blueberries for the pie = 3 pounds.
Now, to get the pounds of blueberries he need to buy more we subtract number of pounds Horace buys blueberries for the pie from Horace needs blueberries for the pie:




Therefore,
pounds of blueberries he need to buy more.
