Answer 1

Answer:

C. $12.80\:dollars$.

Step-by-step explanation:

It was given that,

"Ahmad bought 5 ounces of salad greens for $4.00".

But it was given that, (1 pound = 16 ounces)

We need to convert 5 ounces to pounds.

If 1 pound = 16 ounces, then

$1\:ounce=\frac{1}{16}\:pounds$

This implies that, 5 ounces

$5\times 1\:ounce=5\times \frac{1}{16}\:pounds$

$\Rightarrow 5\:ounces=\frac{5}{16}\:pounds$

The unit rate per pound is

$=4\:dollars \div \frac{5}{16} \:pounds$.

We multiply by the reciprocal of the second fraction to get,

$=4\times \frac{16}{5}$.

$=\frac{64}{5}$

$=12.80\:dollars$.
