Final answer:
To find the weight of Nina's package, divide the total cost paid ($32.67) by the cost per ounce ($0.45), resulting in a weight of approximately 72.6 ounces.
Step-by-step explanation:
To calculate the weight of Nina's package, we need to divide the total cost Nina paid by the cost per ounce. The total cost is $32.67 and the cost per ounce is $0.45. Therefore, we perform the following calculation:
Weight of the package = Total cost / Cost per ounce
Weight of the package = $32.67 / $0.45 per ounce
Weight of the package = 72.6 ounces (rounded to one decimal place)
It's important to note that when mailing a package, understanding the weight in ounces is crucial since the cost of postage is based on this measurement.
