From the computation of the equation, it can be deduced that the change in water level will be -7.955 centimeters.
Since we're given the information that over 18.5 days, a pool's water level changed by an average of −0.43 centimeter each day, therefore, the total change in the water level will be gotten by multiplying the figures given.
Therefore, this will be:
= 18.5 × -0.43
= -7.955
