The office manager of a small office ordered 120 packs of printer paper. Based on average daily use, she knows that the paper will last about 40 days. What graph represents this situation? How many packs of printer paper should the manager expect to have after 10 days?
Not sure if it would be 30packs or 90packs. Then if the graph would go up or down.
If someone could explain how to work this out it would be helpful
120Packs/40days = 3 Packs/Day.
P = 120 - 3*10 = 90 Packs remaining after 10 days.
1. P = 120 - 3x..
P = The number of packs remaining after X days.
3 = The # of packs used per day.
Use the following points fr graphng:

Thank you that is what I finally figured but wasn't sure about the graph
To determine the graph that represents this situation, we need to understand the relationship between the number of packs of printer paper and the number of days. In this case, the office manager knows that 120 packs of paper will last about 40 days. This implies that the office uses an average of 3 packs of paper per day (120 packs ÷ 40 days = 3 packs/day).
Now, let's plot this on a graph. We can represent the number of days on the x-axis and the number of packs of paper on the y-axis.
Since the office uses 3 packs of paper per day, the graph will show a constant downward slope. We start with 120 packs and subtract 3 packs for each day that passes. Therefore, the graph will go down from left to right.
To determine how many packs of paper the manager should expect to have after 10 days, we can use the following calculation:
Number of packs after 10 days = 120 packs - (3 packs/day × 10 days)
= 120 packs - 30 packs
= 90 packs
So, the manager should expect to have 90 packs of printer paper after 10 days.
To summarize, the graph representing this situation is a straight line with a downward slope from left to right. The number of packs of printer paper after 10 days would be 90 packs.
