Algebra.Com's Answer #155190 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! In a new community, the sales representative tells you that there are 38 homes being built, with two floor plans. Floor Plan#1 sells for $175,000 and floor Plan #2 sells for $200,000. She mentions that all the available houses combined are worth $7,200,000. Write an equation that illustrates the solution, also use elimination to determine how many houses with each floor plan are available \n" ); document.write( "---- \n" ); document.write( "Equations: \n" ); document.write( "Quantity Eq.: x + y = 38 \n" ); document.write( "Value Eq:::175000x+200000y = 7200000 \n" ); document.write( "--------------------------------------------- \n" ); document.write( "Modify the 2nd equation: \n" ); document.write( "175x + 200y = 7200 \n" ); document.write( "------------- \n" ); document.write( "Multiply thru the 1st equation by 175 to get: \n" ); document.write( "175x + 175y = 175*38 \n" ); document.write( "------------------------- \n" ); document.write( "Subtract that from the equation above to get: \n" ); document.write( "25y = 550 \n" ); document.write( "y = 22 (# of $200,000 homes) \n" ); document.write( "---- \n" ); document.write( "Since x + y = 38, x = 16 (# of $175,000 homes) \n" ); document.write( "================================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
