Question 189853: Sales, given in thousands, for a particular company in 1990 were at 140.5 and in 2000 at 180.5. Estimate the sales for the years 1997 and 2003. Let x = 0 correspond to 1990. Using the distance formula, find the approximate distance between the values in 1997 and 2003. Explain the difference between using the distance formula and simply subtracting the 2 estimated values.

In this problem, we need to do Double Interpolation since you got 2 unknown values. (You can do graphing too if you prefer).

Let us see the data given:

A 1990 ----- E 140.5
B 1997 ----- F x
C 2000 ----- G 180.5
B 2003 ----- H y

Solving for x:

Cross mutiply

----->
= F, Sales for 1997

Solving for y

Cross multiply

= H, Sales for 2003

Distance between values of 1997 & 2003:

H - F = 192.50 - 168.50 = 24, Answer

Thank you,
Jojo
