To find the weight in ounces of one box, you can calculate the unit rate from the given relationship.
You have: \[ \frac{165 \text{ ounces}}{11 \text{ boxes}} \]
To find the weight per box, divide the total ounces by the number of boxes: \[ \text{Weight per box} = \frac{165 \text{ ounces}}{11 \text{ boxes}} = 15 \text{ ounces per box} \]
Thus, the weight of one box is 15 ounces per box.
