Question

As water evaporates from a potted plant, its weight changes at a rate of- 15/8ounces per day

Part A -Estimate the change in the potted plant's weight after one week.Explain your thinking.
Part B-Write and solve an equation using exact values to show the change in theplant's weight after one week.
Part C-Explain how your estimate shows your answer is reasonable.​

Answer 1

The change in the potted plant's weight after one week is estimated to be -105/8 ounces. The estimate is reasonable because it shows a decrease in weight, which is expected as water evaporates from the plant.

Step-by-step explanation:

Part A:

To estimate the change in the potted plant's weight after one week, we can multiply the rate of change per day by the number of days in a week. The rate of change is -15/8 ounces per day, so the change after one week would be (-15/8) * 7 = -105/8 ounces.

Part B:

To write and solve an equation using exact values, we can set up the equation:
Change in weight = (-15/8) * 7
Change in weight = -15/8 * 7
Change in weight = -105/8 ounces

Part C:

The estimate shows that the potted plant's weight decreased by -105/8 ounces, which is a reasonable change for one week. The negative sign indicates that the plant lost weight, which is expected as water evaporates from the plant.
