Consider the rising cost of postcards over time. The data and scatterplot are provided in the following:

Develop a mathematical model to predict:

(a). when the cost might be $0.50 and

(b). what the cost might be in 2020.

For Projects 2-9, use the software you developed in Project 1 to find the splines that pass through the given data points. Use graphics software, if available, to sketch the resulting splines.
