We will first plot the points that we get from the data. We can notice it creates a graph that looks like the graph of an exponential function. Hence, this data can be modeled by the exponential function $y=a.b^x$ By using a graphing calculator, we find that $a=67.4\\b=1.08$ Hence, the model for the given data is $y=67.4(1.08)^x$
