Question

Jenny's bakery sells carrot muffins at $2 each. The electricity to run the oven is $120 per day and the cost of making one muffin is $1.40. How many muffins does she need to sell in order to break even each day.

Answer 1

Let x be the number of muffins.

Given, $2x = $1.40x + 120

               2x - 1.40x = 120

                   0.6x = 120

                     x = 120/0.6

                        = 200.

Muffins she need to sell  = 200

Hope this helps!

Answer 2

Solution :-

Let the number of muffins needed to sell in order to reach the break even point be 'x'

One time cost i.e. electricity to run the oven + Cost of making one muffin = $ 120 + $ 1.4x

Revenue generated per muffin is $ 2 = 2x

⇒ 120 + 1.4x = 2x

⇒ 120 = 2x - 1.4x

⇒ 120 = 0.6x

⇒ x = 120/0.6

⇒ x = 200

So, Jenny will have to sell 200 muffins each day to reach the break even point.
