Question

on Saturday there was a -4 change in inventory. How many phones were In inventory on Sunday?

Answer 1

14

Explanation:

First we can find Wednesdays inventory by doing 16-5, giving us 11

We can do the same thing for Saturday. Doing -2+20 because the change was positive 20, not negative. That brings Saturdays inventory to 18

They said Saturdays change was -4

So taking the 18 and subtracting 4 gets you Sundays inventory of 14
