Answer 2

Answer:

The cost per pound is $1.75.

Step-by-step explanation:

I feel like the best way to solve this is through ratios.

Write what we know and what we have to find out:

$\frac{20}{35} *\frac{1}{x}$

Cross multiply:

35 * 1 = 35

Now divide:

35/20 = 1.75

The cost per pound is $1.75.
