Rudik [331]
1 cup = 128 grams
X cups = 96 grams

Cross multiply
128X = 1*96
X=96/128 cups = 6/8 = 3/4 cups.

If she has already added 1/2 cups, then she needs to add (3/4-1/2)=1/4 cup more sugar.

Also please remind her to do the calculations before adding ingredients to avoid ruining a recipe.

Brilliant_brown [7]
I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 SEE ATTACHED IMAGE.
 The first thing that we are going to do in this case is to find the slope of the line for the function that simulates the amount of food of the elephant.
 We have then:
 m = (y2-y1) / (x2-x1)
 Substituting any two points:
 m = (625-125) / (5-1)
 m = 125 pounds / day
 125> 13.5
 Answer:
 The elephant eats more than the tiger daily.
