Respuesta :

Answer:

D. She needs to add one over four of a cup.

Step-by-step explanation:

We are given that,

Jessica needs to mix 96 grams of sugar into the flour.

She knows that,

1 cup has 128 grams of sugar.

She added [tex]\frac{1}{2}[/tex] cup of sugar.

So,  [tex]\frac{1}{2}[/tex] cup of sugar has [tex]128\times \frac{1}{2}[/tex] = 64 grams of sugar.

Thus, the amount of sugar she needs to add = 96 - 64 = 32 grams

That is, [tex]\frac{1}{4}[/tex] cup of sugar needs to be added.

Hence, option D is correct.
