To find out how many golf balls the store sold in total, we can calculate the total number of boxes sold and then multiply by the number of golf balls per box.
-
First, calculate the total number of boxes sold: \[ \text{Total boxes} = 10 \text{ (Friday)} + 12 \text{ (Saturday)} = 22 \text{ boxes} \]
-
Next, calculate the total number of golf balls sold: \[ \text{Total golf balls} = \text{Total boxes} \times \text{Golf balls per box} = 22 \text{ boxes} \times 122 \text{ golf balls/box} \]
Now, perform the multiplication: \[ 22 \times 122 = 2684 \]
So, the store sold a total of 2,684 golf balls.
The correct answer is 2,684 golf balls.
