Algebra.Com's Answer #835521 by Theo(13342)![]() ![]() You can put this solution on YOUR website! A = maria's salary \n" ); document.write( "B = marium's salary \n" ); document.write( "before changing jobs, marium's salary was 24% more than maria's. \n" ); document.write( "equation for that is B = 1.24A \n" ); document.write( "after changing jobs, marium's salary wwas 24% less than her previous salary. \n" ); document.write( "equation for that is: \n" ); document.write( "B = .76B \n" ); document.write( "since B = 1.24A in the first equation, then replace B with 1.24A in the right side of the second equationA to get: \n" ); document.write( "B = .76 * 1.24A \n" ); document.write( "simplify to get: \n" ); document.write( "B = .9424A.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "this suggests that, before she changed jobs, her salary was 24% higher than marium's, and after she changed jobs, her salary was 94.24% as large as mariuum's. \n" ); document.write( "94.24% as large means that it is 5.76% less than marium's (94.24% minus 100% = \n" ); document.write( "-(100 = 94.24) = -5.76%.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "to see if this makes sense, then pick a salary for maria, at random, that makes some kind of sense, like 20,000 per year. \n" ); document.write( "since marium's salary, before she changed jobs, was 24% higher, then marium must have been making 24,800.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "when marium changed jobs, she would have been making .76 * 24,800 = 18,848. \n" ); document.write( "20,000 minus 18,848 = 1,152 \n" ); document.write( "1,152 / 20,000 = .0576. \n" ); document.write( ".0576 * 100, = 5.76%. \n" ); document.write( "marium was now making 1,152 less than 20,000 which is 5.76% less than 20,000 \n" ); document.write( "18,848 is also 18,848 / 20,000 = .9424 as large as 20,000. \n" ); document.write( "multiply that by 100, which makes it 94.24% as large as 20,000.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the figures check out, so the solution looks good.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "i'm not exactly sure what you are looking for, but i get: \n" ); document.write( "marium's new salary is 94.24% as large as maria's, which is 5.76% less than maria's.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
