Chapter 4.3, Problem 39PPS

To determine

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

Answer to Problem 39PPS

Equations to find the size of Denali National Park is $7.52=x+2.78$

Size of Denali National Park is $4.74$ million acres

Explanation of Solution

Given information:The Gates of the Arctic National Park is $2.78$ million acres larger than Denali National Park.

Calculation:

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

From the graph,

Size of Gates of the Arctic National Part is $7.52$ million acres

Size of Denali National Park be $x$ million acres

Also, given that The Gates of the Arctic National Park is $2.78$ million acres larger than Denali National Park.

Therefore, we get

$7.52=x+2.78$

Now, Equation is given as

$7.52=x+2.78$

On solving above equation,

> $\begin{array}{l}x=7.52-2.78\\ x=4.74\end{array}$

Hence, size of Denali National Park is $4.74$ million acres
