Question

The food bill is $800 a month. Person A has paid $600. Person B has paid $200. What does Person B have to pay to Person A so they both pay the same?

Answer 1

The food bill is $800 a month

So, two people each should pay 400 toward the food bill.

Person B must give 200 to person A, because 200 + 200 = 400 and, 600 - 200 = 400.
