Jocelyn has a jar of 54 coins consisting of dimes and quarters. If she has a total of $9.60, how many dimes does she have?
\n" ); document.write( "I have tried to draw it out and set it to 960 but i am just confused
\n" ); document.write( "


\n" );
document.write( "Let number of dimes and quarters be D, and Q, respectively
\n" );
document.write( "Then we get the following:
\n" );
document.write( "Number-of-coins equation:       D +    Q =  54 -------- eq (i)
\n" );
document.write( "Value-of-all-coins equation:  .1D + .25Q =   9.6 ------ eq (ii)
\n" );
document.write( "                           - .25D - .25Q = - 13.5 ------ Multiplying eq (i) by - .25 ---- eq (iii)
\n" );
document.write( "                                  - .15D = - 3.9 ------ Adding eqs (iii) & (ii)
\n" );
document.write( "D, or number of dimes = , or \r
\n" );
document.write( "\n" );
document.write( "**I don't mind working with decimals at all. But, if you DO NOT like working with decimals, you could 
\n" );
document.write( "also convert eq (ii) to integers by multiplying entire equation by 20, and then eq (i) by 2, and then
\n" );
document.write( "subtract either equation from the other. \r
\n" );
document.write( "\n" );
document.write( "You also could've solved eq (i) for either D or Q and substitute that value into eq (ii), and solve for
\n" );
document.write( "the variable, D or Q. Then solve for the other variable.\r
\n" );
document.write( "\n" );
document.write( "You can do the check!! \r
