Question

Jacob helped his grandma peel potatoes for the family's dinner. His grandma peeled 4 times as many potatoes as Jacob peeled. If Jacob's grandma peeled 16 potatoes, how many potatoes did they peel altogether?

Answer 1

All together they peeled 20
J:jacob
G:grandma
4J=G. Since she peeled 4 times as he did
4J=16
J=4
So jacob peeled 4 potatoes
All in all:J+G
4+16=20

Answer 2

This question has two parts. First you know that his grandma peeled 16 potatoes, and if Jacob peeled 4 times as many, you have to multiply the amount his grandma peeled by 4 and then add the total to his grandmas total. So the algebraic setup would be x=16+(16•4) and the answer would be 80.
