Abraham o na le lefatshe le le sa dirisiweng la disekweremetara di le 80. O rekisitse sephatlo sa lefatshe leo ka $50, mme morago ga kgwedi, a rekisa sephatlo sa bone sa lefatshe leo ka $30. Morago o ne a rekisa lefatshe le le setseng ka $3 sekewerekmetara nngwe le nngwe. A ka bona bokae morago ga go rekisa lefatshe la gagwe lotlhe le le sa dirisiweng?

Carla just gave birth to identical octuplets. She dresses 3/4 of them in purple and 1/4 in blue. If all the blue-wearers and 1/3 of the purple wearers also wear bows, what is the percentage chance a baby wearing a bow is wearing purple?
Abraham o rekisitse 1/2 x 80= <<1/2*80=40>>40 disekweremetara tsa lefatshe la gagwe le le sa dirisiweng. 
Morago ga kgwedi, o ne a rekisa 1/4 x 40 = <<1/4*40=10>>10 disekweremetara tsa lefatshe la gagwe.
Ka jalo, palogotlhe ya lefatshe le a le rekisitseng ke 40+10= <<50=50>>50 disekweremetara tsa lefatshe la gagwe.
O saletswe ke 80 - 50 = <<80-50=30>>30 disekweremetara tsa lefatshe tse di tshwanetseng go rekisiwa ka $3 sekewerekmetara nngwe le nngwe. 
Ka jalo o bonye $3 x 30 = $<<3*30=90>>90 ka lefatshe leo.
Jalo he, o bonye palogotlhe ya $50 + $30 + $90 = $<<50+30+90=170>>170.
#### 170 

First find the number of babies wearing purple: 3/4 * 8 babies = <<3/4*8=6>>6 babies
Then multiply that number by 1/3 to find the number of babies wearing purple and bows: 6 babies * 1/3 = <<6*1/3=2>>2 babies
Then subtract the number of purple-wearing babies from the total number of babies to find the number of blue-wearing babies: 8 babies - 6 babies = <<8-6=2>>2 babies
Now divide the number of purple bow babies by the total number of bow babies to find the percentage chance a bow baby wears purple: 2 babies / (2 babies + 2 babies) = 2 babies / 4 babies = .5 * 100% = 50%
