Answer:

Permutation

504 ways

Step-by-step explanation:

The difference between combinations and permutations is ordering. With permutations we DO care about the order of the elements, whereas with combinations we don't.

nPr(9,3)

(9 letters in trapezoid, 3 letter combos)

and it returns 504.

Alekssandra [29.7K]

Answer:

5

Step-by-step explanation:

If Wendy has $27 to buy seeds, and each seed bag costs $5, then:

5 · 5 = 25

5 · 6 = 30

27<30

27>25

So, Wendy is able to buy 5 bags and remain with 2 dollars.
