Question

There is a 10 pack of 2.1 ounce bars, and it costs $15.37, what is the price per ounce?

Answer 1

The 10 pack of 2.1 ounce bars costs 15.37; The price per bar is 15.37/10=1.537;the price per ounce is 15.37/ (10*2.1)= $0.73

Answer 2

So,

There are 10 packs of bars that each weigh 2.1 oz.  The total cost of these bars is $15.37.

To find the price per ounce, we need to divide by the number of packs and the number of ounces.
15.37 * 0.1 = 1.537
$\frac{1.537}{2.1} = 0.73\ (approximated)$

So the cost per ounce is approximately 73 cents.
