Store A will be the better buy.
The price will be $53.70 after sales tax at store A.
Step-by-step explanation:
Price of Jacket at store A = $59.60
Discount = 15%
Discount Amount =
Discount Amount =
Price after discount = Original price - Discount amount
Price after discount = 59.60 - 8.94 = $50.66
Price of Jacket at store B = $50.99
The price at store A becomes less than store B after discount, therefore, buying from store A is better.
Sales tax = 6%
Sales tax amount =
Sales tax amount =
Price after sales tax = Discount price at store A + Sales tax amount
Price after sales tax = 50.66 + 3.0396 = $53.6996
Rounding off to nearest hundredth;
Price after sales tax = $53.70
The price will be $53.70 after sales tax at store A.

A) Since a is last in line, we can disregard a, and concentrate on the remaining letters.
Let's start by drawing out a representation:
_ _ _ _ a
Since the other letters don't matter, then the number of ways simply becomes 4! = 24 ways
b) Since a is before d, we need to account for all of the possible cases.
Case 1: a d _ _ _
Case 2: a _ d _ _
Case 3: a _ _ d _
Case 4: a _ _ _ d
Let's start with case 1.
Since there are four different arrangements they can make, we also need to account for the remaining 4 letters.
Now, for case 2:
Let's group the three terms together. They can appear in: 3 spaces.
Case 3:
Exactly, the same process. Account for how many times this can happen, and multiply by 4!, since there are no specifics for the remaining letters.
c) Let's start by dealing with the restrictions.
By visually representing it, then we can see some obvious patterns.
a b c _ _
We know that this isn't the only arrangement that they can make.
From the previous question, we know that they can also sit in these positions:
_ a b c _
_ _ a b c
So, we have three possible arrangements. Now, we can say:
a c b _ _ or c a b _ _
and they are together.
In fact, they can swap in 3! ways. Thus, we need to account for these extra 3! and 2! (since the d and e can swap as well).
