Answer

Explanation:

Step1: Calculate discount amount

The original price of Box B is $7.99 and the discount percentage is 28%. We convert 28% to a decimal (0.28). The discount amount formula is $Discount = Original\ Price\times Percent\ as\ a\ decimal$. So, $Discount = 7.99\times0.28=$2.2372\approx$2.24$.

Step2: Calculate new sale price

Using the formula $Sale\ Price = Original\ Price - Discount\ Amount$, we substitute the values. $Sale\ Price=7.99 - 2.24=$5.75$.

Step3: Calculate new unit - price

The weight of Box B is 650g. The unit - price formula is $Unit\ Price=\frac{Sale\ Price}{Weight}$. So, $Unit\ Price=\frac{5.75}{650}\approx$0.0088$ per gram.

Step4: Analyze the better - buy

Since we don't know the details of Part 1, assume we had compared Box B with another box before. Now, with the new unit - price of Box B being $0.0088$ per gram, we would need to compare it with the unit - price of the other box (if available). If the unit - price of the other box is higher than $0.0088$ per gram, Box B is a better buy. If it is lower, the other box is a better buy.

Answer:

  1. Discount Amount: $$2.24$
  2. New Sale Price for Box B: $$5.75$
  3. New Unit Price for Box B: $$0.0088$ per gram
  4. Without information about Part 1 and the other box, we cannot determine if the decision changes. If the unit - price of the other box is higher than $$0.0088$ per gram, Box B is a better buy; if lower, the other box is a better buy.
