we have
y -----> is the cost in dollars
x -----> is the year
Looking at the graph we have the points
(1983,5,047) and (1991, 10,019)
To determine the cost in the year 1987, find out the midpoint between the two given points
The formula to calculate the midpoint between two points is equal to

Answer:
x=4
Step-by-step explanation:
3/4x+ 4 = 7
Subtract 4 from each side

3/4x = 3
Multiply each side by 4/3
4/3 * 3/4 x = 3 * 4/3
x = 4
