50/100=0.5

0.5x30=15

0.5x70=35

35-15=20

20 grams of Sugar must be added to obtain a mixture solution that is 70% sugar.

Answer:

20 grams must be added more

Explanation:

Given that:

Total grams of mixture = 50

when 30% mixture is sugar:

30% 0f 50 = 0.3(50) = 15 grams of sugar

when 70% of mixture is sugar:

70% of 50 = 0.7(50) = 35 grams of sugar

So in order to make very sweet iced coffee drink that is 30% sugar (15 grams), 20 grams must be added to make 70% sugar (35 grams)

i hope it will help you!
