Morutabana o dirisa tšhoko e e boleele jwa di-inch di le 5 go kwala dipalo mo letlapeng la bana ba gagwe. Morutabana o rata go boloka tšhoko, ka jalo o leka go dirisa fela 20% ya tšhoko letsatsi le letsatsi. E re ka morutabana a sa kgone go kwala ka tšhoko e khutshwane thata, o dirisa tšhoko gape fa e le khutshwane go feta di-inch di le 2. Ka Mosupologo morutabana o ne a dirisa tšhoko e ntšha. Bana ba gagwe ba ne ba tlhoka thuso e e oketsegileng mo letsatsing leo, ka jalo o ne a feleletsa a kwaditse go feta ka gale. O ne a dirisitse 45% ya tšhoko fa letsatsi le fela. Fa morutabana a boela go diriseng fela 20% ya tšhoko letsatsi le letsatsi, o tla nna le malatsi a le makae pele a dirisa tšhoko eno gape?

Thomas withdraws $1000 in 20 dollar bills from the bank account.  He loses 10 bills while getting home.  After that, he uses half of the remaining bills to pay for a bill.  Thomas then triples his money.  He then converts all his bills to 5 dollar bills.  How many 5 dollar bills does he have?
Morutabana o dirisa 45% ya tšhoko ya gagwe ya di-inch di le 5 ka Mosupologo, kgotsa 5 * .45 = <<5*.45=2.25>>2.25 di-inch.
O sala ka 5 - 2.25 = <<5-2.25=2.75>>2.75 di-inch tsa tšhoko.
Letsatsi le le latelang o tla dirisa 20% ya di-inch di le 2.75, e leng 2.75 * .2 = <<2.75*.2=.55>>.55 di-inch tsa tšhoko tse di dirisitsweng.
Seo se mo tlogela ka 2.75 - .55 = <<2.75-.55=2.2>>2.2 di-inch tsa tšhoko.
Letsatsi le le latelang gape, o tla dirisa 2.2 * .2 = <<2.2*.2=.44>>.44 di-inch tsa tšhoko.
Seo se tla mo tlogela ka 2.2 - .44 = <<2.2-.44=1.76>>1.76 di-inch tsa tšhoko.
E re ka 1.76 e le khutshwane go feta di-inch di le 2, o tla dirisa tšhoko eno gape mo malatsing a le 2.

He withdrew 1000/20=<<1000/20=50>>50 bills
So he has 50-10=<<50-10=40>>40 bills left over
He uses half the bills to pay for something, so he has 40/2=<<40/2=20>>20 bills
He triples his money which gives him 20*3=<<20*3=60>>60 bills
So he has 60*20=$<<60*20=1200>>1200
Converting to 5s means he has 1200/5=<<1200/5=240>>240 bills
#### 240
