In a certain grocery store, strawberries cost $5.60 per pound (5.60 dollars/lb). What is the cost per ounce?

[Express your answer numerically to the hundredths place]

Respuesta :

We want to perform a change of units from pound to ounces.

The equivalence is:

5.60 dollars/lb = 0.35 dollars/oz

We start knowing that the cost per pound is $5.60

We can write this cost as:

c = 5.60 dollars/lb

Now we need to use the relation:

1 lb = 16 oz

Then we can replace the "lb" in the denominator of c by 16 oz, we will get:

c = 5.60 dollars/lb =  5.60 dollars/(16 oz) = 0.35 dollars/oz

Then each ounce of strawberries costs $0.35
