We can write an equation from this question:

(32100)/(8.1) = (x)/(100)
Set the denominators equal:

(396296.296296296)/(100) = (x)/(100) \\ \\ x = 396296

To find the total number of copies, divide the number sold by the percentage sold:


8.1% = 0.081


32,100 / 0.081 = 396,296


Double check by multiplying the answer by 8.1%:


396,296 x 0.081 = 32099.9 = 32,100



Total sold = 396,296
