James o reka dipara tsa ditlhako di le pedi ka kgwedi.  O dirisa $2640 mo ditlhakong ngwaga le ngwaga.  Ka tlwaelo o duelela para nngwe le nngwe ya ditlhako bokae? 

A farmer has 900 eggs. He placed them on a tray, which holds 30 eggs each. How much will the farmer earn if he sells it for $2.5 per tray?
O reka 2*12=<<2*12=24>>24 dipara tsa ditlhako ka ngwaga
Ka jalo o dirisa 2640/24=$<<2640/24=110>>110 ka para
#### 110 

There are 900 / 30 = <<900/30=30>>30 trays that hold 900 eggs.
So, the farmer will earn 30 x $2.5 = $<<30*2.5=75>>75 if he sells it per tray.
#### 75
