Since the pint is reflected over the y-axis, its y-coordinate remains the same.
Point (4, 5) has 4 as its x-coordinate. That is 4 units right of the y-axis. The reflection has -4 as its x-coordinate which is 4 units left of the y-axis.
3w = $9.25 would be the equation in this case. In order to solve it, you must divide $9.25 by 3. $9.25 / 3 = $3.83 (repeating bar over the second 3). The cost of one box of popcorn is $3.83.
