Best ResponseYou've already chosen the best response.0Well let x = quantity of soybean in lb. y = quantity of cornmeal 16x + 8y = 320 x 10% = 32 x + y = 320 Solve the two equations.

Best ResponseYou've already chosen the best response.0let x for 16% y for 8% 0.16X+0.08Y= 320*0.10 X+Y= 320 X=320Y Subtitution X=320Y 0.16(320Y)+0.08Y= 320*0.10 51.2 0.16Y +0.08Y= 32 0.16Y +0.08Y= 3251.2 0.08 Y = 19.2 Y =19.2\0.08 Y =240 X+240= 320 x= 320240 x=80

Best ResponseYou've already chosen the best response.0Solve these equations 0.16x + 0.08y = 32 x + y = 320 You can solve this in many ways. EIther guassian elimination, elimination or substitution. By elimination, Multiply first eq by 100 to get 16x + 8y = 3200 > divide by 8 > 2x + y = 400

Best ResponseYou've already chosen the best response.0Now you have 2x + y = 400 x + y = 320 Subtract first eq by the second, You get x = 400320 = 80 You got x, now solve for y. You know that x +y = 320 so y = 320x = 32080 = 240
