A baker needs 15 lb of cream cheese that contains 20% fat to fill a big order. But his supplier delivers one cream cheese that contains 10% fat, and another that contains 35% fat. How many pounds of each should the baker combine to fill the order?​

fat ingredients = final fat amount

.10x       +   .35(15-x)     =      .20 (15)     

            solve for 'x' the amount of 10% to use    then 35% amount = 15-x
