Abby has 37 coins, consisting only of dimes and quarters, worth $7.45. How many dimes and how many quarters does she have?
\n" ); document.write( "--------------------------------------
\n" ); document.write( "Quantity Equation: d + q = 37
\n" ); document.write( "Value Equation...:10d+25q= 745 cents
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "Modify:
\n" ); document.write( "10d + 10q = 370
\n" ); document.write( "10d + 25q = 745
\n" ); document.write( "------------------------
\n" ); document.write( "Subtract 1st from 2nd to solve for \"q\":
\n" ); document.write( "15q = 375
\n" ); document.write( "q = 25 (# of quarters)
\n" ); document.write( "----------------
\n" ); document.write( "Since d+q = 37, d + 25 = 37; d = 12 (# of dimes)
\n" ); document.write( "=====================================================
