The 3-pack for $2.25 is the better deal with a unit price of $0.75 per drink, compared to the 4-pack for $3.16 with a higher unit price of $0.79 per drink. Here option D is correct.
To determine the better deal between the 4-pack for $3.16 and the 3-pack for $2.25, we need to calculate the unit price for each option. The unit price is the cost per drink.
For the 4-pack:
Unit price = Total cost / Number of drinks
Unit price = $3.16 / 4 = $0.79 per drink
For the 3-pack:
Unit price = Total cost / Number of drinks
Unit price = $2.25 / 3 = $0.75 per drink
Comparing the unit prices, we can see that the unit price for the 3-pack is $0.75 per drink, while the unit price for the 4-pack is $0.79 per drink. Therefore, the better deal is the 3-pack for $2.25.
