Answer:
4 or 8, depending on how you interpret the questions
Explanation:
In order to break even, they have to sell 4 widgets. In other words, to make back the $200 they spent on design, they have to sell 4 widgets. Anything over that is profit. This assumes the entire $50 selling price goes to profit (no other information was given).
x = number of widgets
50x ≥ 200
x ≥ 4
To make another $200 above the break even, they have to sell 4 more widgets for a total of 8.
