Answer:
X = 10
Step-by-step explanation:
The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.
Then all you have to do is solve for the equation.

10 = x
The baker needs to sell 10 muffins in a day to make enough to cover the revenue.
