Question

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 1

The approximate cost during the years 1987 was $7527

Step-by-step explanation:

The midpoint formula is:

`M((x_1+x_2)/(2),(y_1+y_2)/(2))`

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:

`M((1983+1991)/(2),(5021+10033)/(2))=M(1987,7527)`

Thus, the approximation for the year 1987 is $7527
