Answer:
The approximate cost during the year 1987 was $7,533
Step-by-step explanation:
The complete question in the attached figure
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

substitute the values


therefore
The approximate cost during the year 1987 was $7,533
So, to solve this, we use this equation:
3700 + 0.05(3700)
But, if we want to make it shorter:
1.05(3700)
Now you just multiply(you may want to use a calculator)
1.05(3700) = 3885
She will pay $3885
2/3 is it's simplified form
