Sara o batla go ithekela baki e ntšha le dipapetlana di le 2. Baki e a e batlang e ja R30 mme para nngwe le nngwe ya dipapetlana e ja R20. Sara o tlhokometse bana ba baagisanyi ga 4, a amogela R5 nako le nako fa a ba tlhokometse. Batsadi ba gagwe ba mo duela R4 nako le nako fa a rema bojang. Fa Sara a ne a setse a na le R10 pele a simolola go tlhokomela bana, o tshwanetse go rema bojang ga kae pele a ka kgona go reka baki le dipapetlana?

Twenty dozen cups cost $1200 less than the total cost of half a dozen plates sold at $6000 each. Calculate the total cost of buying each cup.
Dipapetlana ka bobedi di tla ja palogotlhe ya R2 * R20 = R<<2*20=40>>40.
Sara o tla tlhoka go boloka palogotlhe ya R30 + R40 = R<<30+40=70>>70 go reka sengwe le sengwe se a se batlang.
Sara o amogetse R4 * R5 = R<<4*5=20>>20 go tswa go tlhokomeleng bana.
Magareng ga dipolokelo tsa gagwe le go tlhokomela bana, Sara o setse a bolokile R10 + R20 = R<<10+20=30>>30.
Sara o tlhoka go amogela R70 - R30 = R<<70-30=40>>40 go tswa go remeng bojang gore a kgone go reka diaparo tsa gagwe.
Sara o tshwanetse go rema bojang ga R40 / R4 = <<40/4=10>>10 gore a kgone go reka baki le dipapetlana.

Since a dozen has 12 items, half a dozen plates are 12/2 = <<6=6>>6
Half a dozen plates sold at $6000 each cost 6*$6000 = $<<6*6000=36000>>36000
Twenty dozen cups cost $1200 less than the total cost of half a dozen plates, meaning the twenty dozen cups cost a total of $36000-$1200 = 34800
Since a dozen has 12 items, twenty dozen cups are 20*12 = <<20*12=240>>240 cups.
If the twenty dozen cups cost $34800, each cup costs $34800/240=$<<34800/240=145>>145
