Question

A scout troop 32 markers along a hiking trail. Each Microway is 9 ounces. On the scale to begin the hike, they put the markers in the backpack. If the empty backpack weighed 3 pounds, how much did the backpack weigh with all the markers in it?

Answer 1

The backpack weighs 21 pounds with all the markers in it.

Explanation:

Since they bring 32 markers and each marker is 9 ounces, the weight of all the markers is 288. We know 288 ounces is 18 pounds, so we add 18 to 3. So the backpack weighs 21 pounds with all the markers in it.
