Chapter 4.3, Problem 40PPS

To determine

To calculate:To write and solve the equation to find the size of Katmai National Park

Answer to Problem 40PPS

Equations to find the size of Katmai National Park is $3.34=y-0.75$

Size of Denali National Park is $4.74$ million acres

Explanation of Solution

Given information:Death Valley National park is $0.75$ million acres smaller than Katmai National Park

Calculation:

Graph showing the area of the six largest national parks of United States is as follows:

From the graph,

Size of Death Valley National Park is $3.34$ million acres

Size of Katmai National Park be $y$ million acres

Also, given that Death Valley National park is $0.75$ million acres smaller than Katmai National Park

Therefore, we get

$3.34=y-0.75$

Now, Equation is given as

$3.34=y-0.75$

On solving above equation,

> $\begin{array}{l}y=3.34+0.75\\ y=4.09\end{array}$

Hence, size of Katmai National Park is $4.09$ million acres
