Question: 1 / 400

What will be the depth of a pond after 15 days if it starts at 60 inches and decreases at a rate of 0.2 inches per day?

60 inches

57 inches

To find the depth of the pond after 15 days, we start with the initial depth of 60 inches and account for the decrease over those 15 days. The rate of decrease is 0.2 inches per day, so we can calculate the total decrease over 15 days by multiplying the daily decrease by the number of days:

Total decrease = Rate of decrease × Number of days

Total decrease = 0.2 inches/day × 15 days = 3 inches.

Now, subtract the total decrease from the initial depth:

Depth after 15 days = Initial depth - Total decrease

Depth after 15 days = 60 inches - 3 inches = 57 inches.

Thus, the depth of the pond after 15 days will indeed be 57 inches. This answer aligns correctly with the calculations, confirming the choice.
