Final answer:
The 150 oz laundry detergent at $16.74 is the Best Buy with a cost of $0.1116 per ounce, compared to $0.1498 per ounce for the 100 oz option at $14.98. Estimated costs for other sizes can be calculated using the cost per ounce of the Best Buy option.
Step-by-step explanation:
To determine which is the Best Buy for laundry detergent, you need to calculate the cost per ounce for each option and compare them. First, divide the total cost of each option by the number of ounces to find the cost per ounce.
- For the 150 oz at $16.74 option: $16.74 / 150 oz = $0.1116 per ounce
- For the 100 oz at $14.98 option: $14.98 / 100 oz = $0.1498 per ounce
The 150 oz detergent offers a lower cost per ounce, making it the Best Buy.
Estimated Costs for Different Sizes
To estimate the cost for other sizes:
- For a 40 oz size at $0.1116 per ounce (from the 150 oz option): 40 oz * $0.1116/oz = $4.464
- For a 90 oz size at $0.1116 per ounce (from the 150 oz option): 90 oz * $0.1116/oz = $10.044
If the pricing trend remains consistent, these would be the estimated costs for 40 oz and 90 oz sizes respectively.
