Carmen o ya kwa fantising go ya go fenya tafole ya bogologolo. O dumela tlhwatlhwa ya ntlha ya R200 mme a tswelela go tlhakanela theko go fitlha a fenya. Tlhwatlhwa ya tafole e oketsega ka R50 nako le nako mme batho ba bangwe ba le 3 ba tlhakanela theko gangwe fela mongwe le mongwe. Carmen o tlhakanela theko morago ga mongwe le mongwe wa batho ba le 3 mme kgabagare a fenya. Tafole e mo jelle bokae, ka diranta?

Sam sells bread. He has a target of selling 120 crates of bread in a week. One week he was closed on Monday and Friday. Over the weekend he sold 20 crates. On Tuesday he sold 15 crates, on Wednesday 12 crates, and Thursday 18 crates. By how many crates was Sam off from his target for the week?
Go na le batho ba bangwe ba le 3 ba ba tlhakanetseng theko ya tafole, ka jalo go na le di-bid tsa batho ba le 3 * R50 ka bid = R<<3*50=150>>150 e e okeditsweng mo tlhwatlhweng ya tafole ke batho ba bangwe.
Carmen le ene o tshwanetse go tlhakanela theko kgatlhanong le motho mongwe le mongwe, ka jalo le ene o oketsa di-bid tsa gagwe tse 3 * R50 ka bid = R<<3*50=150>>150 mo tlhwatlhweng yotlhe. 
Ka jalo mo di-bidding tseno, go nnile le palogotlhe ya R150 + R150 = R<<150+150=300>>300 e e okeditsweng mo tlhwatlhweng ya ntlha ya tafole.
Ka jalo tafole e ja R200 ya tlhwatlhwa ya ntlha + R300 e e okeditsweng = R<<200+300=500>>500.
#### 500 

During the whole week Sam sold 15 + 12 + 18 + 20 = <<15+12+18+20=65>>65 crates.
Sam was off his target by 120 - 65 = <<120-65=55>>55 crates.
