Answer: Becky will have to spend £ 9.6 .

Step-by-step explanation:

The ratio of their ages will be:

Melissa : Becky : Daniel = 13 : 12 : 10

Total amount share = £42

Share of Becky = [tex]\dfrac{12}{12+13+10}\times42[/tex]

[tex]=\dfrac{12}{35}\times42\\\\= 14.4[/tex]

Hence, Becky's share = £14.4

Becky decided to save a third of her share.

Then, Amount she spend = [tex]14.4-\dfrac13 \times 14.4[/tex]

[tex]=14.4-4.8\\=9.6[/tex]

hence, Becky will have to spend £ 9.6 .
