Question 948715
d, how many dimes
n, how many nickels


The description is transcribable into this system of equations:
{{{system(d/n=4,0.1d+0.05n=3.60)}}}


Simplify the system and solve for the two variables.


The money count equation should go something like this:
{{{(0.1d+0.05n)/0.05=3.60/(0.05)}}}
'
{{{2d+n=72}}}
'
The coin relationship equation should be easily understood as this:
{{{d=4n}}}, which can easily be substituted into the simplified money count equation.....
