Gabriel o batla go reka koloi e e lopang P10 000 le founo e e lopang P800. Gabriel o na le P5 000 go tswa go berekeng ka mafelo a beke mme morwarraagwe a mo naya P200 go mo thusa. O tlhoka bokae? 

A farmer extracts 5 liters of milk a day from a cow. Since he has 3 cows, how many more cows does he need to have to produce 25 liters of milk a day?
Dilo tse Gabriel a batlang go di reka di lopa P10 000 + P800 = P<<10000+800=10800>>10 800.
Mme Gabriel o na le P5 000 + P200 = P<<5000+200=5200>>5 200.
Ka jalo, Gabriel o sa ntse a tlhoka P10 800 - P5 200 = P<<10800-5200=5600>>5 600.
#### 5 600 

He extracts 5*3=<<5*3=15>>15 liters of milk in a day.
He should extract 25-15=<<25-15=10>>10 liters more in a day.
For that, he needs 10/5=<<10/5=2>>2 more cows.
