• B. $100.47
• C. $90.97
• D. $116.08

Answer: (A)

To determine the total cost of Mary’s purchases, including the discount and tax, we start by identifying the items and calculating the total cost before applying the discount. Mary buys: - Jeans: $24.99 - Skirt: $32.99 - Shoes: $49.99 First, we find the subtotal of these items: Subtotal = $24.99 + $32.99 + $49.99 = $107.97 Next, we apply the 15% discount to the most expensive item, which in this case is the pair of shoes priced at $49.99. To calculate the discount: Discount = 15% of $49.99 = 0.15 × $49.99 = $7.4985 (approximately $7.50 when rounded) Now, we deduct this discount from the subtotal to get the adjusted total: Adjusted total = Subtotal - Discount Adjusted total = $107.97 - $7.50 = $100.47 Once we have the adjusted total, we now need to include the sales tax of 7.5%. Tax amount = 7.5% of adjusted total = 0.075 × $100.47 = $

To determine the total cost of Mary’s purchases, including the discount and tax, we start by identifying the items and calculating the total cost before applying the discount.

Mary buys:

• Jeans: $24.99

• Skirt: $32.99

• Shoes: $49.99

First, we find the subtotal of these items:

Subtotal = $24.99 + $32.99 + $49.99 = $107.97

Next, we apply the 15% discount to the most expensive item, which in this case is the pair of shoes priced at $49.99.

To calculate the discount:

Discount = 15% of $49.99 = 0.15 × $49.99 = $7.4985 (approximately $7.50 when rounded)

Now, we deduct this discount from the subtotal to get the adjusted total:

Adjusted total = Subtotal - Discount

Adjusted total = $107.97 - $7.50 = $100.47

Once we have the adjusted total, we now need to include the sales tax of 7.5%.

Tax amount = 7.5% of adjusted total = 0.075 × $100.47 = $
