Question

] Anne is a bargain-minded shopper. Normally, her favorite toothpaste costs the same at both of her local supermarkets, but the stores are having competing sales this week. At one store, there is a bonus offer: buy 2, get 1 free. At the other store, toothpaste is being sold at 40 percent off. Anne instantly opts for the first offer. Was that really the less-expensive choice?

Answer 1

Answer:

The correct answer is: The second option.

Explanation:

As Anne is a bargain-minded shopper, she will constantly look for paying less as much as the purchases allow it. To determine which option is the less-expensive in the example, Anne should determine what is the cost per toothpaste unit at each of the two local supermarkets. Thus,

- First option:

• Suppose the price of each toothpaste is "n".
• The store offers is buy 2 and get 1 free.
• Then, Anne is getting 3 toothpastes paying only for 2 or: 2 x n = 2(n).
• It implies the price of each toothpaste is: $\frac{2(n)}{3}=0.67n$

- Second option:

• As the toothpaste price is equal in both stores, it will be "n"
• The store offers a 40% discount on each toothpaste.
• Thus, each toothpaste is only 60% of "n" or: $\frac{60(n)}{100} = 0.6n$

So, the less-expensive choice was the second.
