Janice has 16 coins in her purse. Some of the coins are dimes, some are quarters. The total is $2.65. Write a system of equations to solve how many quarters and dimes are in Janice's ion:
\n" ); document.write( "purse.
\n" ); document.write( "------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity: d + q = 16 coins
\n" ); document.write( "Value:: 10d+25q = 265 cents
\n" ); document.write( "--------------------------------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "10d + 10q = 10*16
\n" ); document.write( "10d + 25q = 265
\n" ); document.write( "-----
\n" ); document.write( "Subtract and solve for \"q\":
\n" ); document.write( "15q = 105
\n" ); document.write( "q = 7 (# of quarters)
\n" ); document.write( "Solve for \"d\":
\n" ); document.write( "d = 16-7 = 9 (# of dimes)
\n" ); document.write( "=============================
