HELP PLEASE WILL GIVE BRAINLIEST!!!
levacccp [35]

1) 5% of saturated fat in one serving

2) 2 grams of dietary fibre

3) 750 calories

4) 9%

5) no

Explanation:

From the chart it is given that 1 serving gives 250 calories of energy while 1 container has 3 servings.

The dietary fibre in 250 calorie serving is 2 grams so on consuming 1 serving you get 2 grams of dietary fibre. It provides bulk to the roughage.

The entire container will give

3*250

= 750 calories in entire container.

If entire container consumed then ( 2grams amounts to 3%)

so three servings, 3*3

      = 9%

No vitamin C is found in the serving.
