If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:
1, 2, 3, 4, 15
10, 20, 30, 40, -75
+2, -2, +99, -99, 25
1, 5, 5, 5, 9
Yes it is less than 4,862
No more than in terms of math means less than or equal to.
P = 2l + 2w
{96 ≤ 2l + 2w
{L ≥ w - 4
Here we see a system of linear inequality in two variables.
You finish.
