Answer 1

The 750-milliliter bottle costs $ 0.0024 per milliliter, while the 1.4-liter bottle costs $ 0.0025 per milliliter, making the 750-milliliter bottle a better value.

Explanation:

Given that 750 ml bottle of medicine costs $ 1.80, while 1.4 liter of the same medicine costs $ 3.50, to work out the cost for each bottle in cents per milliliter, and determine which bottle is better value for money, the following calculations must be done:

1.80 / 750 = 0.0024

3.50 / 1,400 = 0.0025

Thus, the 750-milliliter bottle costs $ 0.0024 per milliliter, while the 1.4-liter bottle costs $ 0.0025 per milliliter, making the 750-milliliter bottle a better value.
