Answer:
$42.88
Step-by-step explanation:
We can set up a cross product fraction ratio to find how much 21 pounds of turkey costs.
[tex]\frac{10}{20.42} = \frac{21}{x}[/tex]
Let's apply the cross multiplication property.
[tex]20.42\cdot21=428.82[/tex]
Now we divide this by 10.
[tex]428.82\div10=42.882[/tex]
This simplifies down to [tex]42.88[/tex].
Hope this helped!
