Gary bought a boat for $9000.  Over the first year it depreciated 30%.  The second year it depreciated another 30%.  The third year it depreciated 20%.  How much is the boat worth after the three years?
Helen o ntse mo hoteleng masigo a le 3, ka jalo o tlhoka go duela 3 * 80 = $<<3*80=240>>240 go a duela.
Loeto lo le longwe la bese lo ne lo ja 80 * 10/100 = $<<80*10/100=8>>8.
Helen o paletse bese makgetlho a le 7, ka jalo o dueletse 7 * 8 = $<<7*8=56>>56 go a duela.
Ka kakaretso, Helen o dueletse 240 + 56 = $<<240+56=296>>296 ka kakaretso.
