Mo letsatsing la ntlha la sekolo, Ava o a bona gore ditsala tsa gagwe e bong Cole le Xavier ba godile thata ka bobetelele mo bokhutlong jwa thuto. Xavier o ne a le boleele jwa di-foot di le 4 mme a gola ka di-inches di le 3. Cole o ne a le boleele jwa di-inches di le 50 mme a gola ka di-inches di le 2 mo bokhutlong jwa thuto.

Johnny's dad brought him to watch some horse racing and his dad bet money. On the first race, he lost $5. On the second race, he won $1 more than twice the amount he previously lost. On the third race, he lost 1.5 times as much as he won in the second race. How much did he lose on average that day?
Sa ntlha, re tlhoka go tlhomamisa gore re bapisa diyuniti tse di tshwanang, ka jalo a re fetole di-foot go nna di-inches. Go na le di-inches di le 12 mo foot e le nngwe. Ka jalo Xavier o ne a le boleele jwa di-inches di le 12 x 4 = <<12*4=48>>48.
Xavier o godile go nna boleele jwa di-inches di le 48 + 3 = <<48+3=51>>51.
Cole o godile go nna boleele jwa di-inches di le 50 + 2 = <<50+2=52>>52.
Pharologanyo fa gare ga boleele jwa ga Cole le jwa ga Xavier jaanong ke di-inches di le 52 – 51 = <<52-51=1>>1. 
#### 1 

On the second race he won $11 because 1+ 5 x 2 = <<1+5*2=11>>11
On the third race he lost $15 because 10 x 1.5 = <<10*1.5=15>>15
He lost a total of $20 on the first and third races because 15 + 5 = <<15+5=20>>20

He lost $9 that day because 11 - 20 = <<11-20=-9>>-9
He lost an average of $3 per race because 9 / 3 = <<9/3=3>>3
