Answer 1

We have the following:

What we must do is calculate in each option is value per one pound

1.

$\frac{54}{18}=3$

The value of the first option is 3$ per pound

the value total is 10*$3 = $30

2.

in the second option you have to convert the ounces to pounds, like this

1 ounce = 0.0625 pounds, 8 ounces * 0.0625 pounds / 1 ounce = 0.5 pounds

$\frac{2}{0.5}=4$

The value of the first option is 4$ per pound

the value total is 10*$4 = $40

3.

$\frac{16}{4}=4$

The value of the first option is 4$ per pound

the value total is 10*$4 = $40

therefore the first option Salt Ridge Farms is the best option.
