To find: the number of months the reservoir contains the same amount of water.
Answer to Problem 33E
The amount of water in reservoir
Explanation of Solution
Given:
During drought:
Reservoir
Reservoir
Concept used:
The intersection of two straight line can be calculated as:
By equating the value of
Set the two equations equal to each other and solve for the point where it is intersects.
Calculation:
The objective is to find the number of months after which two reservoirs have same amount of water.
Let
Verbal model can be written as:
Gallons of gallons lost number =Gallons of- gallon lost number of waters in A per months water in
Equation:
Step1: write a system of linear equations using each side of the original equation.
Let
Step 2: solved by graphing.
The graph intersects between
It is clear from the graph that both the lines intersect at
The graph intersects between
Hence, the amount of water in reservoir
