Nick o tlhopha magareng ga ditiro di le pedi. Tiro ya ntlha e duelela $15 ka oura mo diureng di le 2000 ka ngwaga, mme e mo nageng e e nang le lekgetho la 20% ka botlalo. Tiro ya bobedi e duelela $42,000 ka ngwaga mme e mo nageng e e duelelang $6,000 ya lekgetho la thepa le 10% ya lekgetho mo lotsenolweng lo lo setseng morago ga lekgetho la thepa. Nick o tla dira madi a a kana kang mo tirong e e duelang madi a mantsi a a setseng, fa go bapisiwa le tiro e nngwe?

Erin has 7 lollipops. Her mother gives Erin another 10 lollipops. If Erin gives 3 of her lollipops to Ella, how many lollipops does she have left?
Sa ntlha, bala tuelo ya ngwaga ya Tiro ya ntlha: 2000 hours * $15/oura = $<<2000*15=30000>>30,000
Morago ga moo, bala selekanyo sa lekgetho le Nick a le duelang mo Tirong ya ntlha ka go atisa lotseno lwa gagwe ka 20% ya selekanyo sa lekgetho: .2 * $30,000 = $<<30000*.2=6000>>6,000
Jaanong ntsha makgetho a ga Nick mo lotsenolweng lwa gagwe go bona tuelo ya gagwe ya pele ga makgetho mo Tirong ya ntlha: $30,000 - $6,000 = $<<30000-6000=24000>>24,000
Jaanong ntsha makgetho a thepa a ga Nick mo lotsenolweng lwa gagwe la pele ga makgetho mo Tirong ya bobedi: $42,000 - $6,000 = $<<42000-6000=36000>>36,000
Jaanong atisa lotseno la ga Nick morago ga lekgetho la thepa ka 10% go bona lekgetho la gagwe la lotseno mo Tirong ya bobedi: $36,000 * 10% = $<<36000*10*.01=3600>>3,600
Jaanong ntsha selekanyo sa lekgetho la lotseno mo lotsenolweng la ga Nick morago ga lekgetho la thepa go bona lotseno la gagwe lo lo setseng mo Tirong ya bobedi: $36,000 - $3,600 = $<<36000-3600=32400>>32,400
Jaanong ntsha lotseno lo lo setseng mo tirong e e duelang madi a a kwa tlase (A) mo lotsenolweng lo lo setseng mo tirong e e duelang madi a a kwa godimo (B): $32,400 - $24,000 = $<<32400-24000=8400>>8,400
#### 8400 

Erin has 7 + 10 = <<7+10=17>>17 lollipops
After she gives 3 lollipops to Ella she has 17 - 3 = <<17-3=14>>14 lollipops.
