A 10-oz bottle of juice costs $1.49. A 30-oz bottle cost $4.25. Which is the better buy?
1.49 / 10 = 0.149 per oz.
4.25 / 30 = 0.142 per oz
To determine which is the better buy, we need to compare the price per ounce of each bottle. The formula for finding the price per ounce is to divide the total cost by the number of ounces.
For the 10-oz bottle:
Price per ounce = $1.49 / 10 oz
Price per ounce = $0.149 per ounce
For the 30-oz bottle:
Price per ounce = $4.25 / 30 oz
Price per ounce = $0.142 per ounce
Comparing the price per ounce, we can see that the 30-oz bottle is cheaper at $0.142 per ounce compared to the 10-oz bottle at $0.149 per ounce. Therefore, the 30-oz bottle is the better buy as it provides more juice per dollar.
