Sue o nna mo karolong e monate. Ka letsatsi la bokhutlo la beke, baagelani ba ne ba rera go tshameka Sue. Mo mosong wa Labotlhano, baagelani ba ne ba baya diflamingo tse 18 tsa polasetiki e pinki kwa jarateng ya gagwe Sue. Mo mosong wa Matlhatso, baagelani ba ne ba tsaya nngwetharong ya diflamingo, ba di penta ka mmala o mosweu, mme ba di busetsa kwa jarateng ya ga Sue gape. Morago ga foo, mo mosong wa Sontaga, ba ne ba tlatsa ka diflamingo tse dingwe tse 18 tsa polasetiki e pinki. Motshegare wa Sontaga, go ne go na le diflamingo tse di pinki tse dintsi go feta tse di sweu kae?

Tom plants 10 trees a year.  Every year he also chops down 2 trees a year.  He starts with 50 trees.  After 10 years 30% of the trees die.  How many trees does he have left?
Ka Matlhatso, nngwetharong ya diflamingo tse 18 tsa kwa tshimologong e ne ya tlosiwa mme tsa peniwa ka mmala o mosweu: 18 * 1/3 = <<18 * 1/3 = 6>> 6 diflamingo tse di sweu.
Seno se ne sa tlogela diflamingo tse di pinki di le 18 - 6 = <<18 - 6 = 12>> 12.
Ka Sontaga, go ne ga tlatswa ka diflamingo tse dingwe tse 18 tse di pinki, mme palogotlhe ya nna 12 + 18 = <<12 + 18 = 30>> 30 diflamingo tse di pinki mo jarateng.
Ka kakaretso, go ne go na le diflamingo tse di pinki di le 30 le tse di sweu di le 6 mo jarateng, ka jalo go ne go na le diflamingo tse di pinki di le 30 - 6 tse di sweu = <<30 - 6 = 24>> 24 go feta tse di sweu.

He gets 10-2=<<10-2=8>>8 new trees a year
After 10 years he has 8*10=<<8*10=80>>80 new trees
So he had 80+50=<<80+50=130>>130 trees
He lost 130*.3=<<130*.3=39>>39 trees
That means he had 130-39=<<130-39=91>>91 trees
