Answer:
There is no percent left for other foods
Explanation:
The total energy consumed was:
E = 2x1.2x10⁶ + 3x6.7x10⁵ =
E = 4.41x10⁶ J
Knowing that 1 cal = 4.184 J
1 cal --------- 4.184 J
y ---------------- 4.41x10⁶ J
By a simple direct three rule:
4.184y = 4.41x10⁶
y = 1.05x10⁶ cal
Which is higher than the 2000 calorie daily food intake, so there is no percent left for other foods.
