Algebra.Com's Answer #428584 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Roy and Steve have the same number of coins. Roy has only dimes and Steve has only quarters. If Steve has $1.80 more than Roy does, how many coins does each have? \n" ); document.write( "---------- \n" ); document.write( "Equation: \n" ); document.write( "Quantity Eq:: d = q \n" ); document.write( "Value Eq:: 25q = 10d +180 cents \n" ); document.write( "------ \n" ); document.write( "Substitute for \"d\" and solve for \"q\": \n" ); document.write( "25d = 10d + 180 \n" ); document.write( "15d = 180 \n" ); document.write( "d = 12 (# of dimes Roy has) \n" ); document.write( "------ \n" ); document.write( "q = 12 (# of quarters Steve has) \n" ); document.write( "==================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============== \n" ); document.write( " |
