Answer:
8 trees
Explanation:
Since a single 15-year old tree can produce 700 bags and we need to find the number of trees needed to produce 5,600 bags, we therefore need to divide this 5,600 by 700. This will give us the total number of 15-year old trees that will be needed in order to obtain all of the grocery bags.
5,600 / 700 = 8 trees
Finally, we can see that 8 15-year old trees will produce a total of 5,600 paper bags for the store.
