Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 feet per day. Write an equation for the water level, L after d days.
In how many days will the water level be 26 feet



Answer :

The linear function that represents the water level is L = -0.5d + 34 while the number of days will the water take to level 26 feet is 16 days.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given,

Initial water level = 34 feet

Rate of receding = 0.5 feet per day = -0.5

New level L = -0.5d + 34

For the level to be 26 feet,

26 = -0.5d + 34

0.5d = 34 - 26

d = 16 days

Hence "The equation L = -0.5d + 34, which represents the water level, states that it will take 16 days for the water to reach a level of 26 feet".
