Carlos bought 80 feet of wire for $16.80 . 80 needs 30 more feet. If the unit price is the same, how will he pay for the extra 30 feet wire?

$6.30

Step-by-step explanation:

What you would do is that you know 3x2 is 6 just like 8x2 is 16 but then you but the same amount for the cents so the anwser would be $6.30

i think the correct option is the second option.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
