Fa Sally a ntse a tsamaya a ya sekolong, o ne a tshwere megala ya dibalune tse dikhunwana tse 25, tse tala tse 7, le tse ditshetlha tse 12. Ka tshoganyetso, phefo e kgolo e ne ya thuba 40% ya dibalune tse dikhunwana. Modumo o o boitshegang o ne wa tshosa Sally, mme a iphosolosa a lesa sephatlo sa dibalune tse ditshetlha. Mme fa a ntse a atamela sekolo, a bona dibalune tse 8 tse diputswa di kgakgatshegile mo setlhareng, mme a tlhakanya 75% ya tsona le tse di setseng, tse a neng a tsena natso mo sekolong. Ke dibalune di le kae tse a neng a tsena natso mo sekolong kwa bofelong? 

A store offers sandwiches in 3 different package sizes: the first package with 2 sandwiches for $3, the second with 4 sandwiches for $6, and a third with 8 sandwiches, but the price is not indicated. Knowing that the prices are proportional, how much will the package with 8 sandwiches cost?
Sally o simolotse ka dibalune tse dikhunwana tse 25, tse tala tse 7, le tse ditshetlha tse 12, palogotlhe e le 25+7+12=<<25+7+12=44>>44 dibalune.
Mme 40% ya dibalune tsa gagwe tse dikhunwana tse 25 di ile tsa thubega, mo go rayang gore o ne a saletswe ke dibalune tse dikhunwana tse 0.4*25=<<0.4*25=10>>10 fela. 
Modumo o mogolo o ne wa dira gore a lese sephatlo sa dibalune tsa gagwe tse ditshetlha tse 12, mo go rayang gore o ne a saletswe ke (1/2)*12=<<12-6=6>>6 fela ya dibalune tse ditshetlha.
O ne a tlhakanya 75% ya dibalune tse diputswa tse 8 tse a di boneng, mo go rayang gore o ne a tlhakanya dibalune tse diputswa tse 0.75*8=<<75*.01*8=6>>6 mo go tse a neng a ntse a na le tsona. 
Ka jalo, o simolotse ka dibalune di le 44, mme tse dikhunwana di le 10 tsa thubega, tse ditshetlha di le 6 tsa fofa, mme a tlhakanya tse diputswa di le 6, palogotlhe e nna 44-10-6+6=<<44-10-6+6=34>>34 dibalune

So the price for 1 sandwich is $3 / 2 sandwiches = $<<3/2=1.5>>1.5/sandwich
Now the price for the package with 8 sandwiches would be $1.5/sandwich * 8 sandwiches = $<<1.5*8=12>>12
