2.88 is the answer 
..

Answer 2

Answer:

$2.88 per pound

Step-by-step explanation:

For this exercise we must know that 1 dollar is equal to 100 cents and 1 pound is equal to 16 ounces. So the conversion factors are:

1 dollar - 100 cents

1 pound - 16 ounces

so lets start converting the cents into dollars:

$(18\frac{cents}{ounce} )(\frac{1 dollar}{100 cents} ) = 0.18 \frac{dollar}{ounce}$

we use the conversion factor so the cents cancel each other.

Now we convert the ounces into pounds:

$(0.18\frac{dollar}{ounce} )(\frac{16 ounce}{1 pound} )=2.88\frac{dollar}{pound}$

the ounces have to cancel the ounces too with the conversion factor.
