John o ikaeletse go boloka madi a a a bonang kwa tirong.  O duelwa R2 ka hora mme o bereka diura di le 5 ka letsatsi mo malatsing a le 4 ka beke.  Fa e le gore o batla go boloka R80 o tla tsaya dibeke di le kae?

Bill is trying to figure out how many water bottles he needs to buy for his party.  He started out with 2 cases of water which have 24 bottles each. He has 70 guests that will be arriving, and he wants to have 2 bottles of water for each guest. How many additional bottles of water will he need to buy?
O duelwa R2*5=R<<2*5=10>>10 ka letsatsi.
Ka jalo o duelwa R10*4=R<<10*4=40>>40 ka beke.
Seo se raya gore o tla tsaya dibeke di le 80/40=<<80/40=2>>2 go boloka madi a a lekaneng.

Bill has 2 cases of 24 bottles each, so he has 24 * 2 = <<2*24=48>>48 bottles of water
Bill needs enough water for 70 guests to have 2 bottles each, so he needs 70+70 = <<70+70=140>>140 bottles of water.
Bill needs 140 bottles of water and has 48, so he needs to buy 140- 48 = <<140-48=92>>92 bottles of water.
