John o hira tirelo ya go kgweetsa go mo isa tirong letsatsi le letsatsi.  Tiro ya gagwe e dikilometara di le 30 go tswa kwa lapeng mme o tshwanetse go ya le go boa letsatsi le letsatsi.  O ya tirong malatsi a le 5 mo bekeng go ya dibeke di le 50 ka ngwaga.  O duelela R2 go ya ka kilometara nngwe le nngwe e o e tsamayang mme gape o neela mokgweetsi wa gagwe bonase ya R150 ka kgwedi.  O duela bokae ka ngwaga go kgweetsa?

Carmen goes to an auction to win an antique desk. She accepts the opening bid of $200 and continues bidding until she wins. The bids on the desk rise by $50 each time and 3 other people each bid once. Carmen bids after each of the 3 other people and eventually wins. How much money, in dollars, does the desk cost her?
O tshwanetse go tsamaya 30*2=<<30*2=60>>60 dikilometara ka letsatsi
Seo se raya gore o tsamaya 60*5=<<60*5=300>>300 dikilometara ka beke
Ka jalo o duela 300*2=R<<300*2=600>>600 ka beke
Seo se raya gore o duela R600*50=R<<600*50=30000>>30000 ka ngwaga go kgweetsa
Gape o neela R150*12=R<<150*12=1800>>1800 ka ngwaga jaaka bonase go mokgweetsi wa gagwe
Ka jalo o duela R30000+R1800=R<<30000+1800=31800>>31,800 ka ngwaga
#### 31800 

3 other people are bidding on the desk so there are 3 bids * $50 per bid = $<<3*50=150>>150 added to the cost of the desk by other people.
Carmen also has to bid against each person, so she also adds 3 bids * $50 per bid = $<<3*50=150>>150 to the overall cost.
So in these bids, there has been a total of $150 + $150 = $<<150+150=300>>300 added to the initial cost of the desk.
The desk therefore costs $200 opening bid + $300 added cost = $<<200+300=500>>500.
