Bob o ne a na le ditlhapi di le 7 mo bodibeng jwa gagwe jwa ditlhapi tsa mekgabiso. Tse 3 e ne e le tsa mmala wa namune, mme tse 4 e le tsa mmala o mosweu. O ne a swetsa ka gore o batla go oketsa tse dingwe, ka jalo a ya kwa lebenkeleng la diphologolo tse di ruilweng.  Modiri wa kwa lebenkeleng la diphologolo tse di ruilweng o ne a mo kha di le 17 mo teng ga tanka e e nang le mefuta e mebedi ya ditlhapi tsa mmala o mosweu le wa namune. Fa a di fitlha kwa gae a bo a di tsenya mo bodibeng jwa gagwe, o ne a lemoga gore jaanong o na le palo ya ditlhapi tsa mmala wa namune e e gapetsweng gabedi go feta ya tsa mmala o mosweu.  Ke ditlhapi di le kae tsa mmala o mosweu tse Bob a di rekileng kwa lebenkeleng?

Four friends ordered four pizzas for a total of 64 dollars. If two of the pizzas cost 30 dollars, how much did each of the other two pizzas cost if they cost the same amount?
Bob o simolotse ka ditlhapi di le 7 mme a reka di le lesome le bosupa, ka jalo o ne a na le  7 + 17 = <<7+17=24>>24 ditlhapi.
A re re x = palo ya ditlhapi tsa mmala o mosweu.
Bob o na le palo ya ditlhapi tsa mmala wa namune e e gapetsweng gabedi go feta ya tsa mmala o mosweu, ka jalo 2*x + x = 24 ditlhapi
3*x = 24
x = 24/3 = <<24/3=8>>8 ditlhapi tsa mmala o mosweu.
Bob o simolotse ka ditlhapi di le 4 tsa mmala o mosweu, ka jalo o rekile 8 - 4 = 4 ditlhapi tsa mmala o mosweu kwa lebenkeleng.
#### 4 

The other two pizzas cost 64-30 = <<64-30=34>>34 dollars.
Each of the other two pizzas cost 34/2 = <<34/2=17>>17 dollars each.
