Algebra.Com's Answer #677477 by Theo(13342)![]() ![]() You can put this solution on YOUR website! let x equal the regular price of the yogurt. \n" ); document.write( "the sale price of the yogurt is therefore x - .12. \n" ); document.write( "he has to buy 8 in order to get the sale price. \n" ); document.write( "he doesn't want to spend more than 10 dollars.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "your equation becomes: \n" ); document.write( "8 * (x - .12) <= 10. \n" ); document.write( "simplify to get 8 * x - 8 * .12 <= 10. \n" ); document.write( "simplify further to get 8 * x - .96 <= 10 \n" ); document.write( "add .96 to both sides of this equation to get 8 * x <= 10.96 \n" ); document.write( "divide both sides of this equation by 8 to get x = 10.96 / 8 \n" ); document.write( "solve for x to get x = 1.37\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the regular price is 1.37 \n" ); document.write( "the sale price is .12 less than this. \n" ); document.write( "this makes the sale price equal to 1.25. \n" ); document.write( "8 * 1.25 is equal to 10.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "regular price of 1.37 is your solution. \n" ); document.write( " \n" ); document.write( " |
