Algebra.Com's Answer #27206 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! You have at least $30.00 in change consisting of dimes and quaters. \n" ); document.write( "What's the least number of coins you can have? If you could have all quarters, \n" ); document.write( "that would be the least number, but you must have some dimes. \n" ); document.write( "All quarters would be $30/.25 = 120 coins. \n" ); document.write( "You can't take away 1 quarter to get change in dimes. You must take away 2 \n" ); document.write( "quarters, and get 5 dimes change. \n" ); document.write( "120 coins - 2 quarters + 5 dimes = 123 \n" ); document.write( "That's the low end of the inequality. \n" ); document.write( "The most coins you could have would be all dimes. \n" ); document.write( "That would be $30/.10 = 300, but you must have quarters. Dimes don't \n" ); document.write( "divide evenly into 1 quarter, but there are 5 dimes in 2 quarters. \n" ); document.write( "300 coins - 5 dimes + 2 quarters = 297 \n" ); document.write( " \n" ); document.write( "for exactly $30 worth of dimes and quarters \n" ); document.write( " |
