Algebra.Com's Answer #314265 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! an errand boy went to deposit some bills for his employer. some were one-dollar bills and the rest were five-dollar bills. the total value of the bills was $86 and the number of bills was 38. Find the number of each kind of bill. \n" ); document.write( "====================================== \n" ); document.write( "Let x = the number of five-dollar bills \n" ); document.write( "Since the total number of bills is 38, the number of one-dollar bills will be 38-x \n" ); document.write( "Then we can write the following equation for the total $ amount: \n" ); document.write( "1*(38-x) + 5x = 86 \n" ); document.write( "Solve for x: \n" ); document.write( "38 - x + 5x = 86 \n" ); document.write( "4x = 48 \n" ); document.write( "x = 12 \n" ); document.write( "Therefore, the number of 5-dollar bills is 12 \n" ); document.write( "And the number of 1-dollar bills is 38-12 = 26 \n" ); document.write( " |
