A horse and a cow together cost $800.the horse is sold a a profit of 10% and the cow at a loss of 10%. If the total profit of 2.5% is made,what is the cost price of the horse? \n" ); document.write( ": \n" ); document.write( "Let x = cost of the horse \n" ); document.write( "then \n" ); document.write( "(800-x) = cost of he cow \n" ); document.write( ": \n" ); document.write( "Horse profit = .1x \n" ); document.write( "Cow loss = -.1(800-x) \n" ); document.write( ": \n" ); document.write( "Total profit = .025(800) = 20 \n" ); document.write( ": \n" ); document.write( ".1x - .1(800-x) = 20 \n" ); document.write( ".1x - 80 + .1x = 20 \n" ); document.write( ".2x = 20 + 80 \n" ); document.write( "x = \n" ); document.write( "x = $500 cost of the horse \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check our solution: \n" ); document.write( "Cow cost = 300 \n" ); document.write( ".1(500) - .1(300) = \n" ); document.write( "50 - 30 = 20 \n" ); document.write( " |
