During a 6-week drought, the water
level in the lake decreases by 6 inches
each week. To find the overall change in
the water level, we need to multiply the
decrease per week by the number of
weeks.
First, let's calculate the decrease in the
water level each week: 6 inches/week x
6 weekS =36 inches.
Therefore, the overall change in the
water level over the course of a 6-week
drought is a decrease of 36 inches.
