The logical approach would be to look at the totals, as you're trying to get the class favourite. Looking at such values, we see that Spiderman is the most trending, with the higher frequency, making it the class favourite.
Question 3. You divide 5 1/4 by 3/4 then multiply that by 20.
The answer is 140
Let W = width of package
Let H = height of package
Let L = length of package
The perimeter cab be one of the following:
P = 2(L + W), or
P = 2(L + H)
The perimeter of the cross section cannot exceed 108 in.
When the width is 10 in, then
2(L + 10) <= 108
L + 10 <= 54
L <= 44 in
When the height is 15 in, then
2(L + 15) <= 108
L + 15 <= 54
L <= 39 in
To satisfy both of these conditions requires that L <= 39 in.
Answer: 39 inches
