Question

A donut shop owner spends $3 to make one dozen cinnamon rolls. He marks them up 500% to sell to customers. What is the price for one dozen cinnamon rolls?

Answer 1

The price for one dozen cinnamon rolls is $18.

Explanation:

We are given the following in the question:

Money spend on making one dozen of cinnamon rolls = $3

Marked price = 500% of the making cost

We have to find the price for one dozen cinnamon rolls.

Marked Price =

`500\% * 3\\\\=(500)/(100)* 3\\\\=15`

Selling price = Marked price + Cost price

`=15+3\\=\$18`

Thus, the price for one dozen cinnamon rolls is $18.
