Question 121754
"Find the increase in sales from 2002 to 2006":

To find the increase, simply subtract {{{5.8*10^10}}} (remember this is the number 58,200,000,000) from {{{9.08*10^10}}}  (this is the number 90,800,000,000)


{{{9.08*10^10-5.82*10^10}}} Subtract



{{{10^10(9.08-5.82)}}} Factor out {{{10^10}}}



{{{10^10(3.26)}}} Subtract {{{9.08-5.82}}} to get {{{3.26}}}



{{{3.26*10^10}}} Multiply note: this is the number $32,600,000,000



So from 2002 to 2006, the sales increased by {{{3.26*10^10}}} dollars




--------------------------------------------


"Find what percent that increase is of the 2002 sales"



Now to find the percent, simply divide {{{5.8*10^10}}} by {{{3.26*10^10}}}:




{{{(5.8*10^10)/(3.26*10^10)=5.8/3.26=1.779}}}



Now multiply {{{1.779}}} by 100 to get the percentage


{{{1.779*100=177.9}}}



So the percent increase is 177.9%
