Go na le kobo nngwe ya mawelana le kobo nngwe ya mawelana a mararo. Ngwana a le mongwe wa mawelana o mogolo ka dingwaga di le 7 mo go ngwana a le mongwe wa mawelana a mararo. Fa dingwaga tsa bone tsotlhe di kopane di le 44, ngwana a le mongwe wa mawelana o na le dingwaga di le kae?

Catherine goes to the grocery store. She buys 1 kilo of apples for $4, 2 kilos of bananas for $2 per kilo, and 2 kilos of oranges for $3 per kilo. How many dollars does she pay in total?
A re re T = dingwaga tsa ngwana wa mawelana a mararo
Dingwaga tsa ngwana wa mawelana = T + <<+7=7>>7
Dingwaga tsa mawelana di kopane = 2 * (T + 7)
Dingwaga tsa mawelana a mararo di kopane = <<3=3>>3T
2 * (T + 7) + 3T = 44
2T + 14 + 3T = 44
5T + 14 = 44
5T = 30
T = <<6=6>>6
Ngwana wa mawelana = 6 + 7 = <<6+7=13>>13
Ngwana wa mawelana o na le dingwaga di le <<13=13>>13.

1 kilo of apples costs $<<1*4=4>>4.
2 kilos of bananas costs 2 * 2 = $<<2*2=4>>4.
2 kilos of oranges costs 2 * 3 = $<<2*3=6>>6.
She pays 4 + 4 + 6= $<<4+4+6=14>>14 in total.
