Edna buys a bottle of dog shampoo that costs 3.99$. The bottle contains 28.5 ounces of shampoo. What is the cost per ounce of shampoo?

Respuesta :

Answer: $0.14 per ounce

Step-by-step explanation:

There are 28.5 ounces of shampoo in the shampoo bottle and the cost of the whole bottle is $3.99.

The cost per ounces will therefore be:

=  Cost of bottle / Number of ounces

= 3.99 / 28.5

= $0.14 per ounce
