12. donna sent her grandson a birthday present. the box weighed 0.875 kilograms and the
present itself weighed 6,800 grams.
a. what was the gross weight of the package in kilograms?
b. if shipping costs 74 cents per kilograms, how much did the package cost to send, in
dollars?

Explanation:

1 kg = 1000 grams

0.875 kg = 0.875 * 1000 = 875 grams.

The gross weight = 6800 + 875 grams = 7675 grams

The gross weight = 7675 / 1000 = 7.675 kg.

1 kg costs 74 cents = 74/100 = 0.74 dollars.

7.675 kg costs 0.74 dollars

Cost = 7.675 * 0.74

Cost = 5.68 dollars.
