In these two columns, the same nested IF function is used in cells B10 through B19. (It uses relative cell references.)

What is most likely the function entered into cell B10?

=IF(OR(A10>-3,A10<-1),A10*0.5 ,A10)
=IF(AND(A10>-3,A10<-1),A10*0. 5,A10)
=IF(OR(A10<-3,A10>-1),A10*0.5 ,A10)
=IF(AND(A10<-3,A10>-1),A10*0. 5,A10)

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)
