g = grams of 99% cocoa
0.99g = value of 99% cocoa
200 - g = grams of 70% cocoa
0.70(200 - g) = value of 70% cocoa
0.86(200) = value of mixture
0.99g + 0.70(200 - g) = 0.86(200)
Solve for g, grams of 99% cocoa
200 - g = grams of 70% cocoa
0.99g = value of 99% cocoa
200 - g = grams of 70% cocoa
0.70(200 - g) = value of 70% cocoa
0.86(200) = value of mixture
0.99g + 0.70(200 - g) = 0.86(200)
Solve for g, grams of 99% cocoa
200 - g = grams of 70% cocoa
