If prunes cost $2.90/lb and apricots cost $3.15/lb and a total of 20 lbs of the two combined was sold for $59.75. How many pounds of each fruit was sold?
\n" ); document.write( ":
\n" ); document.write( "A standard mixture problem, learn this method and you can do most of these type of problems.
\n" ); document.write( ":
\n" ); document.write( "Let x = no. of lbs of prunes
\n" ); document.write( ":
\n" ); document.write( "The two fruit amts add up to 20, so we can say:
\n" ); document.write( "(20-x) = no of lbs of apricots
\n" ); document.write( ":
\n" ); document.write( "2.90(x) + 3.15(20-x) = 59.75
\n" ); document.write( ":
\n" ); document.write( "2.9x + 63 - 3.15x = 59.75
\n" ); document.write( ":
\n" ); document.write( "2.9x - 3.15x = 59.75 - 63
\n" ); document.write( ":
\n" ); document.write( "-.25x = -3.25
\n" ); document.write( ":
\n" ); document.write( "x = -3.25/-.25
\n" ); document.write( ":
\n" ); document.write( "x = +13 lb of prunes
\n" ); document.write( ":
\n" ); document.write( "then 20 - 13 = 7 lb of apricots
\n" ); document.write( ":
\n" ); document.write( ":
