To determine which is the better buy, we need to calculate the price per liter of water for each option.
Option 1: Twelve 710mL bottles of water for $6.60.
The total volume of water in this option is 12 bottles * 710mL = 8,520 mL.
To convert this to liters, we divide by 1,000: 8,520 mL / 1,000 = 8.52 L.
The price per liter is $6.60 / 8.52 L = $0.77/L.
Option 2: Twenty-four 500mL bottles of water for $9.18.
The total volume of water in this option is 24 bottles * 500mL = 12,000 mL.
To convert this to liters, we divide by 1,000: 12,000 mL / 1,000 = 12 L.
The price per liter is $9.18 / 12 L = $0.765/L.
Comparing the prices per liter, we can see that option 2 ($0.765/L) is cheaper than option 1 ($0.77/L).
Therefore, twenty-four 500mL bottles for $9.18 is the better buy.
To determine which option is the better buy, we can calculate the cost per milliliter (mL) of water for each option.
Option 1: Twelve 710mL bottles for $6.60
The total volume of water is 12 * 710mL = 8,520mL.
The cost per milliliter is $6.60 / 8,520mL ≈ $0.000774 per mL.
Option 2: Twenty-four 500mL bottles for $9.18
The total volume of water is 24 * 500mL = 12,000mL.
The cost per milliliter is $9.18 / 12,000mL ≈ $0.000765 per mL.
Comparing the cost per milliliter, we can see that Option 1 has a slightly lower cost per milliliter ($0.000774 per mL) compared to Option 2 ($0.000765 per mL). Therefore, Twelve 710mL bottles for $6.60 is the better buy in terms of cost per milliliter of water.
