Johnny o tsere madi a gagwe a a mo abelwang a $20 mme a tlhakanya le a mangwe a $10. Morago o ne a beeletsa madi a, mme a menagane gararo mo ngwageng. O ne a na le madi a makae morago ga ngwaga? 

Ram uses a lot of pens. He discovered that he can save money by mixing the ink from five empty pens to make one full pen. If he buys 25 pens and then uses them to make new pens when the ink runs low, how many total pens does he get to have?
Johnny o beetseditse madi a masome a mabedi le a lesome ebong palogotlhe ya 20+10=<<20+10=30>>30 dollars
Madi a a menagane gararo mo ngwageng, mme palogotlhe ya 30*=90 dollars
#### 90 

He can make 5 pens when the 25 run low because 25 / 5 = <<25/5=5>>5
He can make 1 pen when the ink in the re-made pens runs low because 5 / 1 = <<5/1=5>>5
He will have 31 total pens because 25 + 5 + 1 = <<25+5+1=31>>31
