Baithuti mo tlelaseng ya 3B ba kgobokanya dintlha tsa boitshwaro. Fa ba ka kgona go bona dintlha tse di lekaneng, ba tlaa ya loetong. Mo tlelaseng, go na le Adam, Martha, Betty, le Tom. Adam o kgobokantse dintlha di le 50. Betty o dirile botoka go feta Adam mme a kgobokanya 30% go feta. Marta o kgonne go kgobokanya dintlha go menagane gatlhano go feta Tom, yo o nang le dintlha di le 30 kwa tlase ga Betty. Ke dintlha di le kae tse di tlhaelang tlelase gore e ye loetong fa boleng jo bo tlhokegang e le dintlha di le 400?

Tomorrow, 42 adults and 15 babies will be attending a function at Mia’s restaurant. The restaurant has 5 times as many regular chairs as high chairs. If there are 8 high chairs, how many more chairs does she have to get?
Betty o na le 30% ya dintlha tse di fetang tsa ga Adam, ka jalo ke 30/100 * 50 = <<30/100*50=15>>15 dintlha tse di fetang.
Palogotlhe ya ga Betty ke 50 + 15 = <<50+15=65>>65 dintlha.
Tom o na le dintlha di le 30 kwa tlase ga Betty, ka jalo o na le 65 - 30 = <<65-30=35>>35 dintlha.
Marta o na le dintlha go menagane gatlhano go feta Tom, ka jalo o na le 3 * 35 = <<3*35=105>>105 dintlha.
Ka kakaretso, baithuti botlhe ba kgobokantse 50 + 65 + 35 + 105 = <<50+65+35+105=255>>255 dintlha.
Ka jalo tlelase e tlhaela 400 - 255 = <<400-255=145>>145 dintlha gore e ye loetong.
#### 145 

Since there are 8 high chairs, the number of regular chairs is 5 * 8 = <<8*5=40>>40 regular chairs
The total number of both types of chairs is therefore 8 + 40 = <<8+40=48>>48 chairs
However, the total number of attendants will be 42 + 15 = <<42+15=57>>57 people
Mia will therefore need 57-48 = <<57-48=9>>9 more chairs
