A can of soda in 1972 costs $0.21, by 2012 it cost $1.30.

Find the rate at which the cost of a can of soda increases over this time period.

(round to the thousandths place)

Construct a linear model that can be used to predict the cost of soda.

y =x +where x = number of years since 1972

Use your linear model to predict the cost of soda in 2014.
