Question

1. a small wading pool had 10 inches of water in it. it rained and the water level went up 1 inch. then the water level went down 3 inches after children splashed some water out. write an expression that best represents the level of water in the wading pool. use the keyboard to enter the correct answer in the box.

Explanation:

Step1: Identify initial water level

The initial water level is 10 inches.

Step2: Add the rise in water level

After raining, the water level went up 1 inch, so we add 1 to the initial level: $10 + 1$.

Step3: Subtract the drop in water level

Then the water level went down 3 inches, so we subtract 3 from the previous level: $(10 + 1) - 3$.

Step4: Calculate the final level

Simplify the expression: $10 + 1 - 3 = 8$.

Answer:

8
