Answer:
girl aged 12 years received $32
girl aged 15 years received $ 40
Step-by-step explanation:
1. add ages together 12 + 15 = (27)
2. use your answer 27 , as your denominator
to those ages , and multiply them with $72
[tex] \frac{12}{27} \times 72 = 32 \\ \\ \\ \frac{15}{27 } \times 72 = 40 \\ \\ \\ \\ 32 + 40 = 72[/tex]
OR
girl aged 12 years old (a) 12÷27× $72
= $32
girl aged 15 years old (b) 15÷27×$72
= $40
(here's a proof $32 + $40)
