The purchasing power p of a fixed income of $20000 per year (such as a pension) after t years of 7% inflation can be modeled by p=20000(1.07)^t find the purchasing power after 5 years fin the purchasing power after 20 years

After 5 years: 107,000

After 20 years: 428,000

Step-by-step explanation:

While I can not give you the exact answer as it is a graph, it's worth noting that the function is in f(x) = mx + b form.

This means the first point with an x coordinate of 0 will start at 6, and for each increase in one on the x-axis, we add 2.4.

So, the first coordinate is (0,6), the next is (1,8.4), and so on until you reach the end. That shouldn't take very long provided you can compute addition mentally.

Hope this helps and Good Luck
