lets see. let x be the the weight in pounds of bird seeds. that makes the weight of sunflower seeds to be 40x. since total cost = price x amount, then \[0.59\left( x \right)+0.89\left( 40x \right)=0.76\left( 40 \right)\]\[59x+89(40x)=76(40)\]\[59x+3560 89x=3040\]\[30x=520\]\[x=\frac{ 52 }{ 3}=17\frac{ 1 }{ 3 }\]therefore, the weight of birdseeds must be 17 1/3 pounds while the weight of sunflower seeds is 4017 1/3 = 22 2/3 pounds. and sorry i misled....
