Answer: Second buy is better
Explanation:
From the question, we are informed that a certain shampoo is available in two sizes:
A 14.2-ounce bottle costs $33. The unit price will be:
= $33 / 14.2
= $2.32 per ounce
9-ounce bottle costs $9.98. The unit price will be:
= $9.98 / 9
= $1.11
The second size is the better buy.
