Jovante decides to start a business by making buttons and selling them for 25 cents each. The button machine costs $125 and the materials for each button cost 10 cents.

If he wants to sell buttons, say 40 buttons, he will get a profit of 1000 cents. And one dollar is equal to 100 cents so he only earns 10 dollars. However, the costs for the machine are 125 dollars. Therefore he has a loss of 115 dollars.
