## The Problem

Nocona Lake is drying up. The lake loses about 4 feet of water every week.

What is Nocona's water level after 7 weeks if the water is 64 feet deep?

64-(7x4) =

## The Constant

The constant is -4, beacuase it never ever changes and will aalways stay the same. A constant is a variable that never changes

## The Independent Variable

The independent variable is the weeks, because it does not rely on any other variable and will not change becuase of another An independent variable is a variable that depends on nothing.

## The Dependent Variable

The dependent variable is the water level, because the water level depend's on the weeks(the Independent variable) and the amount of water it loses every week ( The constant -4). A Dependent variable is a variable that depends on the independent variable and the constant.

## Graph Explanation

This is the correct and accurate (Its drawn, so its a not perfect) because the water level (in blue) is decreasing steadily over time as they water dries up.

## Solved question

64-(7x4) solve the problem in parenthesis

64-28 solve the problem

36

After 7 weeks the water will be at 36 feet. The lake lost 36 feet
