Permutation: In a race of 10 students, find the number of ways students can finish 1st, 2nd, and 3rd. In this case the order matters, so it is a permutation.
10 x 9 x 8 = 720 ways
Combination: In a class of 10 students, find the number of ways a group of 3 students can be selected to win a prize. In this case the order doesn't matter, so it's a combination.
10 x 9 x 8 / (3 x 2 x 1) = 120 ways

Answer:
28 biscuits
18 packages of pemmicans
4 packages of butter and cocoa
Step-by-step explanation:
We are given percentage of total daily calories for each item.
Since total number of calories per person each day is 5600,then;
Number of calories from biscuit daily = 40% × 5600 = 2240 calories
Since there are 80 calories per biscuits, then number of biscuits = 2240/80 = 28 biscuits
Number of calories from pemmican daily = 45% × 5600 = 2520 calories
Since there are 140 calories per package, then number of packages of pemmican = 2520/140 = 18 packages of pemmicans
Number of calories from butter and cocoa daily = 15% × 5600 = 840
Since there are 210 calories per package, then number of packages = 840/210 = 4 packages of butter and cocoa
