Question

use the graph to determine the solution to the system of equations. interpret the solution in terms of the problem situation. old growth forests are forests that have not experienced unnatural or man - made disturbances. currently, the united states has about thirteen thousand square miles designated as old growth forest, and this is increasing at the rate of 340 square miles a year. the logging industry proposes that it be permitted to harvest 990 square miles of old growth timber per year. enter the answer in each space provided. use numbers instead of words. in (square) years, the size of the growth forest will be equal to the amount harvested under the logging industrys proposal. that size is (square) thousand square miles.

Explanation:

Step1: Identify intersection point

The two lines on the graph intersect at the coordinate $(20, 19)$.

Step2: Map to problem variables

The x-value represents time in years, and the y-value represents area in thousands of square miles.

Answer:

In 20 years, the size of the growth forest will be equal to the amount harvested under the logging industry's proposal.
That size is 19 thousand square miles.
