Fern o leka go tlhopha go reka mochini wa Widgeteer 3000, o o dirang di-widget di le 60 ka ura, le WidgetMaster 9000, o o dirang di-widget di le 45 ka ura. Widget e le nngwe e rekisiwa ka R6. Ke madi a makae a a oketsegileng a Fern a tla a dirang ka Widgeteer 3000 go feta WidgetMaster 9000 fa e bereka diura di le 24 ka letsatsi mo kgweding ya malatsi a le 30?

A charity group decides to do a yard sale.  10 people donate 5 boxes of stuff each.  They also have 10 boxes of stuff already.  They can fit 2 boxes worth of stuff per table.  If they already own 15 tables, how many new tables do they need?
Sa ntlha bona gore Widgeteer 3000 e dira di-widget di le kae ka ura: di-widget di le 60/ura - di-widget di le 45/ura = <<60-45=15>>di-widget di le 15/ura
Morago ga moo atisa pharologanyo eo ka palo ya diura mo letsatsing go bona pharologanyo ya letsatsi: di-widget di le 15/ura * diura di le 24/letsatsi = <<360=360>>di-widget di le 360/letsatsi
Morago ga moo atisa pharologanyo ya letsatsi ka palo ya malatsi mo kgweding go bona pharologanyo ya kgwedi: di-widget di le 360/letsatsi * malatsi a le 30/kgwedi = <<360*30=10800>>di-widget di le 10,800/kgwedi
Morago ga moo atisa palo eo ka tlhwatlhwa ya widget e le nngwe go bona pharologanyo ya palogotlhe ya madi a a dirwang: di-widget di le 10,800/kgwedi * R6/widget = R<<10800*6=64800>>64,800
#### 64800 

There were 10*5=<<10*5=50>>50 donated boxes
So they have a total of 50+10=<<50+10=60>>60 boxes
So they need a total of 60/2=<<60/2=30>>30 tables
That means they need 30-15=<<30-15=15>>15 tables
#### 15
