Question 183213
<pre><font size = 4 color = "indigo"><b>
Sam found a N nickels, D dimes, and Q quarters in his room. He found three more
dimes than nickels (D = N+3), but twice as many quarters as dimes (Q=2D). The
total value of the coins was $5.05 (5N + 10D + 25Q = 505). How many coins of
each type did Sam find? Please show me the steps you took to get your answer;
I am totally lost!

Edwin's solution:

{{{system(D = N+3, Q=2D, 5N+10D+25Q=505)}}}

Can you solve that system? If not post again, asking how.

Answer: 5 Nickels, 8 Dimes, 16 Quarters
