Answer 5

Let d and q be the number of dimes and quarters respectively.
Solve the following equations for d and q:
\[{10 d + 25 q = 635, d = 3 + 3 q} \]\[{d = 36, q = 11} \]

Answer 6

Ok.

Answer 7

Is that it?

Answer 8

10 d + 25 q /. {d -> 36, q -> 11}
635
Yes, that is it.

P.S.
With these types of coin problems it is cleaner to work with pennies.
