a baker has a bag of flour that is 11%whole wheat and a bag of flour that is 63%whole wheat. how many cups of each type does the baker need to make 12 cups of a flour mixture that is 50% whole wheat

Hi Jacqueline

to get 50% whole wheat
u add 11% whole wheat and 63% whole wheat in the ratio
(63-50):(50-11)
= 13:39
= 1:3
i.e u add 1 cup of 11% whole wheat to 3 cups of 63% whole wheat to obtain 4 cups of 50% whole wheat
SO
u add 3 cups of 11% whole wheat to 9 cups of 63% whole wheat to obtain 12 cups of 50% whole wheat

3 cups of flour that is 11% whole wheat and 9 cups of flour that is 63% whole wheat.

Personal Mathematical knowledge

let n = number of cups of 11%
Balancing the meal……0.11 x n + (12 – n ) 0.63 = 12 x 0.50
From this, we see n = 3 cups of 11%……….so we use 9 cups of 63%
