brand a dish detergent costs $2.48 and is 21.6-ounces. Brand b costs $1.55 and is 12.9 ounces. Which brand is the better buy? Explain

Answers

Answer:


Brand A

Step-by-step explanation:

To determine which brand of dish detergent is the better buy, we need to compare the price per ounce of each brand.

Brand A:

  • Price: $2.48
  • Size: 21.6 ounces

Brand B:

  • Price: $1.55
  • Size: 12.9 ounces

To calculate the price per ounce, we divide the price by the size:

  • \texttt{Brand A: \$2.48 /$ 21.6 ounces = \$0.115 per ounce}
  • \texttt{Brand B: \$1.55 /$ 12.9 ounces = \$0.120 per ounce}

Based on the calculations, Brand A has a lower price per ouncecompared to Brand B. Therefore, Brand A is the better buy in terms of cost efficiency.

Answer: Brand A

Brand A gives more value

Step-by-step explanation:

Brand A Is the better buy. Why? Because you will get more value from it. 2.48 multiplied by 21.6 is 53, while with brand B, 1.55 multiplied by 12.9 is 19.9. You will get more value from Brand A than B.
