Lemonade Stand Profit Calculation

A group of five friends decided to start a small business selling lemonade during the summer. They initially invested a total of $150 to purchase all the necessary supplies. Each friend agreed to contribute an equal amount for the initial investment. After their first day of selling lemonade, they made a total of $90 in sales. They decided to reinvest half of their earnings back into the business for additional supplies. The remaining amount was split equally among the five friends as their profit.

How much money did each friend receive as profit after reinvesting half of the earnings?
