> First let us compute for the total sales the three people made.
Total sales = $2030 + $1540 + $1800 = $5370
Therefore the fractional sales are:
Lola = $2030/$5370 = 203/537 = 0.378
Ahmed = $1540/$5370 = 154/537 = 0.287
Tommy = $1800/$5370 = 180/537 = 0.335
> The bonus they each received is:
Lola = 0.378 ($100) = $37.8
Ahmed = 0.287 ($100) = $28.7
Tommy = 0.335 ($100) = $33.5
