document.write( "Question 1172284: A painter needs a custom color for a large mural he is painting. To make the custom painting he must add four units of blue and 3 units of magenta to each quart of paint. The painter knows that a gallon of paint will cover 350 sq ft. He also knows that 4 quarts equals 1 gallon. How many units of magenta will he need for the mural which is 1200 square feet. Round your answer \n" ); document.write( "

document.write( "The ratio of the areas is  1200/350 = 24/7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the ratio of the paint volumes is  24/7, too.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The number of units of magenta is 3 per each quart, or 3*4 = 12 units per gallon.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the number of units of magenta is  24/7 times 12, or   =  = 41  for the mural of 1200 sq ft.\r\n" );
