Question 1161056
---------------------
total value of $83.75. There are twice as many dimes as nickels, and 50 more quarters than dimes.
--------------------


{{{system(d/n=2,q-d=50)}}}


{{{n/d=1/2}}}
{{{n=d/2}}}


-

{{{q=d+50}}}

-

Sum of money $83.75;
{{{5n+10d+25q=8375}}}
{{{n+2d+5q=1675}}}


Substitute to have equation in only variable, d:
{{{highlight_green(d/2+2d+5(d+50)=1675)}}}--------solve this for d, and use for finding the other two.


First result:  {{{highlight_green(d=190)}}}
