<PRE><B>Question 949308</B>
I have 30 total coins that total $3.55. There are 3 more dimes than nickels. How many quarters do I have.
5n+10(n+3)+25(30-2n+3)=355
5n+10(n+3)+25(30-(2n+3))=355
5n+10(n+3)+25(30-2n-3)=355  **************** The -1 applies to the 3

--------------
n = # of nickels
Solve for n
5n+10(n+3)+25(30-2n-3)=355
5n + 10n+30 + 750-50n-75 = 355
-35n + 705 = 355
-35n = -350
n = 10 nickels
