7 : 21
which can be simplified to 1 : 3 as both sides are divisible by 7
Rewrite in standard form using (h,k) to find the vertex.
(3,4) is the answer.

We can write an equation in terms of n, the amount of nickels:
25(3n+3)+10(n+1)+5n=265.
Thus:
90n+85=265
Subtracting 85, we have:
90n=180
Therefore, n=2. As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
It all depends on the size of a student and the age.
