Answer 1

Answer:

$\begin{gathered} \\ B\colon\text{ \ 5.04} \end{gathered}$

Explanation:

Here, we want to get the unit price per pound

From the question, the brand sells for $3.15 per 10 ounces

Mathematically, 1 ounce is 0.0625 pound

Thus $3.15 is the price for 0.625 pounds (10 * 0.0625 pounds)

if $3.15 is for 0.625 pounds

$x will be for 1 pound

Mathematically:

$\begin{gathered} 3.15\times1\text{ = 0.625}\times x \\ x\text{ = }\frac{3.15}{0.625} \\ x\text{ = \ 5.04} \end{gathered}$
