Answer:
Step-by-step explanation:
We are given that Jenna knits scarves and sells them on Etsy an online market place.

Where C=Represents the cost in dollars
x=Number of scarves
We have to create a table to show the relationship between the number of scarves x and the cost C
Substitute x=1
$24
Substitute x=2
$28
$32
$36
$40
$44
<span>2x + x = 12
=> x =12/3 =4
so, original number is 84. </span>
