Lori o ne a tlhoka lee le le lengwe le le feletseng go dira dikarolwana di le pedi tsa mae a a bedisitsweng. O akanya gore mongwe le mongwe wa baeng ba gagwe o tla ja dikarolwana di le tharo tsa mae a a bedisitsweng. Fa a laletsa baeng ba le 16 mo moletlong wa gagwe, o tla tlhoka dimatla tsa mae di le kae?

James hires a horse-drawn carriage from 5 PM to 9 PM.  He gets 1 hour free.  The first paid hour is $15 and each hour after that is twice the cost.  How much did he pay?
O laletsa baeng ba le 16 ba ba tla jang dikarolwana di le tharo tsa mae a a bedisitsweng mongwe le mongwe ka jalo o tlhoka 16 * 3 =<<16*3=48>>48 dikarolwana 
Go tlhokega lee le le lengwe le le feletseng go dira dikarolwana di le pedi ka jalo dikarolwana di le 48 ke 48 / 2 = <<48/2=24>>24 mae a a feletseng
Tsatsi e le nngwe e lekana le 12 mme o tlhoka mae a le 24 ka jalo o tlhoka 24 / 12 = <<24/12=2>> dimatla di le 2 tsa mae

He got it for 9-5=<<9-5=4>>4 hours
He pays for 4-1=<<4-1=3>>3 hours
The first hour cost 1*15=$<<1*15=15>>15
The other 3-1=2 hours are more expensive
They cost 15*2=$<<15*2=30>>30 per hour
So those 2 hours cost 2*30=$<<2*30=60>>60
So he pays 60+15=$<<60+15=75>>75 per hours
