Answer:
- GH₵10.50 per girl
- GH₵20.50 per boy
Explanation:
Given GH₵960 contributed by 80 students of which 68 are girls who contributed a total of GH₵714, you want to know the amount per girl and the amount per boy that was contributed.
Rate
The amount per girl or boy is found by dividing their total contribution by the corresponding number of girls or boys.
Application
If 68 girls contributed GH₵714, then the amount per girl is ...
(GH₵714)/(68 girls) = GH₵10.50 /girl
Each girl contributed GH₵10.50.
The remaining 12 students were boys, and the amount they contributed was (GH₵960 -714) = GH₵246. Then the amount per boy is ...
(GH₵246)/(12 boys) = GH₵20.50 /boy
Each boy contributed GH₵20.50.
