Question

During the summer months, the water level in Marta's pool decreases by about 1/2 inch each day due to evaporation. Which equation shows the approximate total change, in inches, to the water level in her pool after 30 summer days?

Answer 1

15 because I just did this answer and 15 was correct

Answer 2

Answer: 15.

Explanation:

Total decrease = decrease per day × number of days.

The decrease per day is 1/2 and the number of days is 30.

So, we can multiply 30 × 1/2 = 15.

The final water level will depend on the initial water level in the pool.

Hopes this helps!
