Mark o ne a sa ikutlwe sentle dikgwedi di le 3, mme mo dikgweding tseo o ne a latlhegelwa ke dikilogerama di le 4.5 kg ka kgwedi. Fa boima jwa gagwe jwa bofelo e ne e le 31.8 kg, boima jwa gagwe jwa ntlha e ne e le bokae?

Elise is learning to write and decides to keep re-writing the alphabet until she knows it. She writes it in full twice, writes half of it once, then re-writes everything she has already written. How many letters has Elise written in total?
E re ka Mark a ne a latlhegelwa ke 4.5 kg kgwedi le kgwedi, mo dikgweding di le 3 o latlhegetswe ke 4.5 * 3 = <<4.5*3=13.5>>13.5 kg.
Fa re kopanya boima jo a bo latlhegetsweng le boima jwa gagwe jwa bofelo, re bona gore boima jwa gagwe jwa ntlha e ne e le 31.8 + 13.5 = <<31.8+13.5=45.3>>45.3 kg.
Boima jwa ntlha jwa ga Mark e ne e le 45.3 kg.
#### 45.3 

**Note:** I have converted pounds to kilograms as this is the standard unit of measurement in Botswana. 

Elise has written the alphabet twice which is a total of 26 * 2 = <<26*2=52>>52 letters.
She then writes half the alphabet, which is 26 / 2 = <<26/2=13>>13 letters.
So far, this is a total of 52 + 13 = <<52+13=65>>65 letters.
Writing this again means she has doubled the number of letters she has written, so she has written a total of 65 * 2 = <<65*2=130>>130 letters.
#### 130
