Indira Melissa decided to sell donuts in an effort to raise funds for a 2021 summer vacation to Italy. Indira went to Dunkin Donuts and spent $300 to purchase 300 donuts. Because she was buying in large quantities, Dunkin Donuts sold each donut to her for $1.00 each. During the week, Indira sold 175 donuts at $2.50 each in front of the campus bookstore at her university. A few of her friends and classmates bought donuts from her and so she gave them discounts totaling $30. Unfortunately, 7 students didnt enjoy the flavor of their donuts and so they returned it to Indira. Because she was using her universitys facilities, she had to pay a rental fee of $50 to the university. She had a friend of hers, Link, who helped her sell and advertise the donut sale. Link charged her $40 for his work. Calculate the following:
