Question

3. The Rule of 72 is used to make a quick estimate of the time required for prices to double due to inflation. If the inflation rate is r percent, then the Rule of 72 esti- mates that prices will double in 72/r years. For instance, at an inflation rate of 6 percent, prices double in about 72/6 or 12 years. Write a program to test the accu- racy of this rule. The program should display a table showing, for each value of r from 1 to 20, the rounded value of 72/r and the actual number of years required for prices to double at an r percent inflation rate. (Assume prices increase at the end of each year.) Figure 6.19 shows the first few rows of the output.
