The graph shows how many cups of food are in an automatic pet feeder after given numbers of days. Which statement is correct?
Coordinate plane with x-axis labeled as days, and the y-axis labeled as cups contains a graph of a line passing through the points (0, 8), (4, 5), and (8, 2).
Question 10 options:
Every day, the amount of food decreases by Mathml image cups.
Every 3 days, the amount of food decreases by 4 cups.
Every 4 days, the amount of food decreases by 3 cups.
Every Mathml image-day, the amount of food decreases by Mathml image cup.
The correct statement is: Every 4 days, the amount of food decreases by 3 cups.
This can be observed from the points on the graph. From (0, 8) to (4, 5), there is a decrease of 3 cups over a period of 4 days. Similarly, from (4, 5) to (8, 2), there is another decrease of 3 cups over a period of 4 days. Therefore, the amount of food decreases by 3 cups every 4 days.
