" For each annual rate of change, find the corresponding growth or decay factor.

17) +45%
18) -10%
19)-40%
20)+200% ...?"

Answer 1

Using formula factor =1+ (rate of change)/100
Where the rate of change is the percent as a whole number

17)
factor =1+ (rate of change)/100
factor =1+45
          =46

18)
factor =1+ (rate of change)/100
factor =1-10
          =-9

19)
factor =1+ (rate of change)/100
factor =1-40
          =-30

20)
factor =1+ (rate of change)/100
factor =1+ 200
          =201
