The length is two inches less than five times the width. This means
Length (L) = 5w - 2. (Does this make sense? You calculate 5 times the width and then minus 2)
Then we know the perimeter of a rectangle is 2(L+w) so
Perimeter = 2(5w-2 + w) = 2(6w-2) = 12w - 4 (so C and D are both correct because they are equal)
We check the other two options manually,
A: 2(5w-2)+2w = 10w-4+2w = 12w - 4 (so A is correct because it equals D which also equals C)
B: w+w+5w+5w-2 = 12w - 2 (which does not equal any of the other options)
So correct answers are A, C and D because they are all equal.

Answer:
1 paperback is $3.55 and 1 notebook is $3.59 and those items cost less than $3.75.
Step-by-step explanation:
3 paperbacks= $10.56
1 paperback= $10.56 ÷ 3 = $3.55
4 notebooks= $14.36
1 notebook= $14.36 ÷ 4 = $3.59
3 puzzles= $11.85
1 puzzle= $11.85 ÷ 3 = $3.95
4 picture frames= $15.20
1 picture frame= $15.20 ÷ 4 = $3.80
