The three numbers are 2, 5, and 11.

The sum of 3 numbers is 18. 2 + 5 + 11 = 18

Since the problem states that every number is a prime number, then the number must be a natural number greater than 1 that has no positive divisors other than 1 and itself.

2 / 1 = 2 OR 2 / 2 = 1 These numbers are prime numbers because their divisors
5 / 1 = 5 OR 5 / 5 = 1 are 1 and itself.
11/1 = 11 OR 11/11 = 1

The price per ounce for the 14.2 ounce bottle is $0.28. The price per ounce for the 33.9 ounce bottle is $0.29. Therefore, the 14.2 ounce bottle of shampoo Is the better buy.

You take the total price of the shampoo bottle and divide it by how many ounces there are to get the price per ounce.
