Answer:
200 muffins
Step-by-step explanation:
The selling price of each muffin = $2
The cost price of each muffin = $1.40
The price of electricity = $120
If the number of muffins that Jenny sells in a day is x, then, Jenny's total cost in a day is:
120 + (1.4 * x) = 120 + 1.4x
and the total sales earnings in a day for x muffins will be:
2 * x = 2x
To break even, the total costs in a day must equal to the total earnings. That is;

Solving this:

She must sell 200 muffins in a day to break even.
I think it would be 4.
8 breaks down to 4(2) and 12 breaks down to 4(3). Let me know if that helps!
3 3/4 this would be your answer hope this is helpful
Here, take any points (0, -2) ((1, -6)
Now, slope (m) = -6 - (-2) / 1 - 0 = -6+2 / 1 = -4
Now, y - y1 = m(x - x1)
y - (-6) = -4(x - 1)
y + 6 = -4x + 4
y = -4x - 2
In short, Your Equation would be y = -4x - 2
Hope this helps!
