You can buy shampoo in a 5-ounce bottle for $3.39 or in an 15-ounce bottle for $9.99.

a) What is the price per ounce for the 5-ounce bottle? (Round to the nearest cent as needed)

b) What is the price per ounce for the 15-ounce bottle? (Round to the nearest cent as needed)

c) Is the 5-ounce bottle or the 15-ounce bottle the better buy?

AHOOOGAHH!!

To find the price per ounce for each bottle, we simply divide the total price of the bottle by its weight in ounces.

a) Price per ounce for the 5-ounce bottle:
To find the price per ounce for the 5-ounce bottle, we divide the total price (which is $3.39) by the weight (which is 5 ounces):

Price per ounce = $3.39 / 5 ounces = $0.678 per ounce

So the price per ounce for the 5-ounce bottle is approximately $0.68.

b) Price per ounce for the 15-ounce bottle:
To find the price per ounce for the 15-ounce bottle, we divide the total price (which is $9.99) by the weight (which is 15 ounces):

Price per ounce = $9.99 / 15 ounces = $0.666 per ounce

So the price per ounce for the 15-ounce bottle is approximately $0.67.

c) Comparing the price per ounce for the 5-ounce and 15-ounce bottles:
Now that we have the price per ounce for each bottle, we can compare which one is the better buy. The lower the price per ounce, the better the value.

In this case, the 15-ounce bottle has a slightly lower price per ounce ($0.67) compared to the 5-ounce bottle ($0.68).

Therefore, the 15-ounce bottle is the better buy if you are looking for the best value based on the price per ounce.
