Question

Ozzie is scooping fertilizer out of a bag containing 8 1/2 pounds. Each scoop removes 5/16 of a pound of fertilizer. How much fertilizer would remain in the bag after 12 scoops are taken out?

Answer 1

First, let's calculate how much are those 12 scoops:

`(5)/(16)\cdot12=3.75`

This way, 3.75 pound would be removed with those 12 scoops.

Therefore,

`8.5-3.75=4.75=4(3)/(4)`

4 3/4 pounds would be left in the bag
