The correct response is:
The time it takes the lake to decrease by 20 inches is 5 weeks.
This is because the equation \(-20 \div -4 = 5\) calculates the number of weeks it takes for the lake to decrease 20 inches at a rate of 4 inches per week.
The height of a lake decreased by 20 inches over several weeks. Each week the lake decreased by 4 inches. The following equation represents this situation:
−20÷−4=5
