Hannah o relela mo kgapetleng ya banana mme a robega letsogo. Ngaka e mo lefisa R200 ya ho mo tlama letsogo, R300/hora bakeng sa ketelo ya metsotso e 30, R4/pilisi bakeng sa di-painkiller tse 30, le R6/hora bakeng sa ho paka koloi bonyane dihora tse 2 tse tlhokehang. Ketelo ya ngaka e bitsa bokae ka kakaretso?

Becky, Jake, and Silvia shared 4 pizzas. Each pizza had 8 slices. Becky ate 3 more slices than Jake did. Silvia ate twice as many slices than Jake did. If Becky ate 10 slices, how many total slices did they eat?
Pele fumana bolelele ba ketelo ka dihora: metsotso e 30 / metsotso e 60/hora = <<30/60=.5>>dihora tse .5
Ebe o fumana ditjeo kaofela tsa ketelo: R300/hora * dihora tse .5 = R<<300*.5=150>>150
Ebe o fumana ditjeo kaofela tsa di-painkiller: R4/pilisi * dipilisi tse 30 = R<<4*30=120>>120
Ebe o fumana ditjeo tsa ho paka koloi: R6/hora * dihora tse 2 = R<<6*2=12>>12
Ebe o eketsa ditjeo tsohle tse fapaneng ho fumana ditjeo kaofela: R12 + R120 + R150 + R200 = R<<12+120+150+200=482>>482
#### 482 

Jake ate 10-3 = <<10-3=7>>7 slices of pizza.
Silvia ate 7*2 = <<7*2=14>>14 slices of pizza.
Jake, Silvia, and Becky ate 10+7+14 = <<10+7+14=31>>31 slices all together.
