Question

George runs a manufacturing business and needs to keep track of the inventory in his warehouse each month. The table shows the change in total inventory at the end of each month last quarter. Month Inventory Change Jan +20 Feb +30 Mar −70 Which number line represents this information?

Answer 1

To represent the inventory changes on a number line for the quarter, you would see an increase for January and February and a decrease in March, ending lower than the starting point.

Step-by-step explanation:

The student asks which number line represents the change in inventory for George's manufacturing business over the last quarter where the inventory changes were: January +20, February +30, and March -70. To create this number line, we would start at a point, add 20 for January, then add 30 for February, followed by subtracting 70 for March, indicating an overall decrease from the starting point.

A correct number line would show an initial increase for the first two months, followed by a sharp decrease in the third month, where the final position is lower than the starting point as a result of the March decrease.
