Answer:
It is better to buy 6 pints at $8.10
Explanation:
To compare the cost per pint in each option, we can divide the total cost by the total number of pints.
For the first option, buying 3 pints at $3.60, the cost per pint is shown by the following:
3 pints ÷ $3.60 = $0.83 / pint
For the second option, buying 6 pints at $8.10, the cost per pint is shown by the following:
6 pints ÷ $8.10 = $0.74 / pint
Therefore, buying 6 pints at $8.10 is less expensive per pint than buying 3 pints at $3.60. Each pint when buying 3 at a time costs $0.83 whereas each pint when buying 6 at a time costs $0.74.
