Question

The number of grocery items on two grocery list differs by 7. The total number of items is 33. How many items are on each list?

Answer 1

Answer: 13 and 20
==================================
Let the number of grocery items on the smaller list be x

Bigger grocery list = x + 7

x + (x + 7) = 33
2x + 7 = 33
2x = 26
x = 13

Smaller grocery list = 13 items
Bigger grocery list
= 13 + 7
= 20

Therefore, there are 13 items on the smaller list while there are 20 items on the bigger list
