We know that Susan has raised $234 by selling 18 equally priced wreaths. So the find the price, y, of one wreath, we need to divide 234 by 18. And that can be done using the equation 18y = 234.
How? 18y = 234
Divide both sides by 18 (18y)/18 = 234/18 y = 234/18 y = 13
So using the equation 18y = 234, we were able to find the price of each wreath: y = $13
