12:18 is a 2:3 ratio of pink to blue
If this ratio continues for the population of the box;
the ratio has 5 parts. 100/5 = 20. Each part is 20.
2 * 20 = 40
3 * 20 = 60
P:B = 40:60
40 pink chips and 60 blue chips

\bf \begin{cases} f(x) = 5x-10\\ g(x) = x + 3 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ g(-1)=(-1)+3\implies \boxed{g(-1) = 2} \\\\\\ f(~~g(-1)~~)\implies f\left( \boxed{2} \right) = 5(2)-10\implies \stackrel{f(~g(-1)~)}{f(2)}=0
