The graph depicts the growth in costs using a line segment. Use the midpoint formula to approximate the cost during the year 1987.The approximate cost during the year 1987 was $ ____.

Answer:
The approximate cost during the years 1987 was $7527
Explanation:
The midpoint formula is:
[tex]M(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]For two given points.
In this case, we can see in the graph the points (1983, 5021) and (1991, 10033)
Then, using the midpoint formula:
[tex]M(\frac{1983+1991}{2},\frac{5021+10033}{2})=M(1987,7527)[/tex]Thus, the approximation for the year 1987 is $7527
