Jenny's Bakery sells carrot muffins for $2.00 each. The electricity to run the oven is $120.00 per day and the cost of making one carrot muffin is $1.40. How many muffins need to be sold each day for the bakery to break even?
The total cost of electricity and materials for one muffin is $1.40 + $120.00 = $<<1.40+120.00=121.40>>121.40.
Jenny's Bakery needs to sell $120.00 / $121.40 = 0.99 muffins each day to break even.
So they need to sell at least 1 muffin each day to break even. Answer: \boxed{1}.
To find the number of muffins that need to be sold each day for the bakery to break even, we need to consider both the fixed costs (electricity) and the variable costs (cost of making one muffin).
Let's assume the number of muffins to be sold each day is represented by 'x'.
The total cost to make 'x' muffins each day is given by the equation:
Total Cost = (Cost of making one muffin) * (number of muffins)
Total Cost = $1.40 * x
The total revenue earned from selling 'x' muffins each day is given by the equation:
Total Revenue = (Selling price of one muffin) * (number of muffins)
Total Revenue = $2.00 * x
For the bakery to break even, the total cost needs to equal the total revenue, so we can set up the following equation:
Total Cost = Total Revenue
$1.40 * x = $2.00 * x
To solve for 'x', we can cancel out the 'x' terms on both sides by subtracting $1.40 * x from both sides:
$2.00 * x - $1.40 * x = 0.60 * x
Dividing both sides by 0.60, we get:
x = ($2.00 * x) / $0.60
x = 3.33
Since 'x' represents the number of muffins, it must be a whole number. Therefore, the bakery needs to sell at least 4 muffins each day to break even.
