Algebra.Com's Answer #15225 by bmauger(101)![]() ![]() ![]() You can put this solution on YOUR website! Call the original price of the jeans x. So 15% of the original price would be 15% times x or .15x. So when we take the orginal price, subtract the discount (since it's \"15% off) we get the equation: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For problem 2, first let's get rid of the \"other bills\" and focus only on tens and twenties. Because he had $147 in other bills, and a total of $1167, that means the total from 10s and 20s must be 1167-147=$1020. \n" ); document.write( "Lets call the number he has of each x. So he has x 10s and he has x 20s. The value from the 10s is 10x (for instance if he had 7 tens the value would be 10*7=70). Likewise the value from the 20s is 20x. When we add the two values we get 10x+20x. Because we already figured that this sum must be $1,020 we can write: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So the teller had 34 tens ($340) and 34 twenties ($680) and the $147 in \"other bills\" for a grand total of $1167. Check. \n" ); document.write( " |
