#### Answer

a). amount of fat in 1 serving is 18g.
Amount of calories provided = $18 \times 9 = 162 $ calories.
% age of calories provided by fat = $\frac{162}{310} \times 100 = 52.2$
b). Maximum amount of fat is as per below :-
$28 = \frac{weight}{2000}\times 100$
$weight = 28\times 20 = 560 g $ of total fat
The maximum amount of saturated fat is calculated as :-
$35=\frac{weight}{2000}\times 100$
$weight = 35 \times 20 = 700 g$ of fat.
