Using her half cup, Jessica added 64 grams of sugar to her mixture. She needs to add 32 grams of sugar to have the right amount.

Answer:

She needs 1/4 cup more

Step-by-step explanation:

1 over 2 = 1/2 = 0.5

1 cup = 128

So, 1/2 cup = 128*0.5 = 64 grams

Since she needs 96, she will need to add more

96-64 = 32

She will need to add 32 grams of sugar

32/128 =0.25

Therefore, she needs 1/4 cup more
