(04.05 mc) the following table shows the expressions that represent the sales of 4 companies: company a b c d sales 110(0.70)x 140(1.07)x 430(1.90)x 310(1.14)x rank the company sales by smallest to largest percent of increase and select the correct answer below. (5 points) a, b, c, d a, b, d, c d, c, b, a d, c, a, b

company a               b                 c               d

sales             110(0.70)^x   140(1.07)^x 430(1.90)^x 310(1.14)^x

in exponential function

where 'r' is the increase rate

lets find percentage of increase for each company

company a =

1+r = 0.70 , so r= -0.30

percentage = -0.30* 100 = -3%

company b =

1+r = 1.07 > r = 1.07 -1 = 0.07 , so r= 0.07

percentage = 0.07* 100 = 7%

company c =

1+r = 1.90 > r = 1.90 -1 = 0.90 , so r= .90

percentage = .90* 100 =90%

company d =

1+r = 1.14 > r = 1.14 -1 = 0.14 , so r= 0.14

percentage = 0.14* 100 = 14%

-3%, 7%, 90%, 14%

now write the percentage in order (smallest to largest)

-3%, 7%, 14%, 90%

so order of company as per percent of increase is a, b, d, c
