Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for
Alona [7]

The equation is L = 34 – 0.5d  for the water level, L, after d days

<h3><u>Solution: </u></h3>

Given that , Suppose that the water level of a river is 34 feet  

And that it is receding at a rate of 0.5 foot per day.  

We have to write an equation for the water level, L, after d days

The equation can be framed for water level after d days which is found by calculating difference between initial level and receding level of water per day

Now , we know that,

<em>water level after d days = initial level – receded level of water. </em>

L = 34 feet – number of days spent x rate of receding level per day.

L = 34 feet – d days x 0.5 foot

L = 34 – 0.5d  

Hence, the equation is L = 34 – 0.5d
