My answer is D am i right?

how did you get it

Yes, D.

To determine the best buy, we need to compare the total cost of each option.

Option A:
The cost to buy online is $15 plus $0.79 per pound for shipping and handling. Since the item is 12 pounds, the total cost would be $15 + ($0.79 * 12) = $15 + $9.48 = $24.48.

Option B:
The cost to buy online is $17 plus $0.69 per pound for shipping and handling. Again, since the item is 12 pounds, the total cost would be $17 + ($0.69 * 12) = $17 + $8.28 = $25.28.

Option C:
When buying at a local store, the item's price is $24.99, and using a $3-off coupon, the total cost would be $24.99 - $3 = $21.99.

Option D:
When buying at a local store, the item's regular price is $22.50, and it is on sale for 10% off. The discount amount would be $22.50 * 0.10 = $2.25. So, the sale price would be $22.50 - $2.25 = $20.25.

Comparing the total costs:
Option A: $24.48
Option B: $25.28
Option C: $21.99
Option D: $20.25

Based on the calculations, Option D is the best buy with a total cost of $20.25. So, your answer is correct.

To determine the best buy, we need to compare the total cost for each option. Let's analyze each option:

A) Buy online for $15 plus pay shipping and handling costs of $0.79 per pound.
To calculate the total cost, we need to add the cost of the item ($15) to the shipping and handling costs ($0.79 per pound x 12 pounds). This gives us: $15 + ($0.79 x 12) = $15 + $9.48 = $24.48.

B) Buy online for $17 plus pay shipping and handling costs of $0.69 per pound.
Similar to the previous option, we add the cost of the item ($17) to the shipping and handling costs ($0.69 per pound x 12 pounds): $17 + ($0.69 x 12) = $17 + $8.28 = $25.28.

C) Buy at a local store where the item’s price is $24.99, and use a $3-off coupon.
In this case, we subtract the coupon value from the item's price: $24.99 - $3 = $21.99.

D) Buy at a local store where the item’s regular price is $22.50 and it is on sale for 10% off.
To find the sale price, we multiply the regular price by (100% - 10%): $22.50 x 0.9 = $20.25.

Comparing the total costs:
Option A: $24.48
Option B: $25.28
Option C: $21.99
Option D: $20.25

Based on the calculations, option D, "Buy at a local store where the item’s regular price is $22.50 and it is on sale for 10% off," has the lowest total cost of $20.25. Therefore, your answer is correct.
