Katrina saw an ad that said if she signed up for her local recycling program, she could earn $5.00. When she signed up, they told her for every friend that she referred, the friend would receive $5.00 and she would receive another $5.00 per friend. That day, she had 5 friends sign up and another 7 friends by the end of the week. How much money in total did she and her friends make?
Thoughts? Step-by-step reasoning:

She signed up 5 friends, then an additional 7 for a total of 5 + 7 = 12 friends. Each friend received $5 so 12 * 5 = $60.00. And she received $5 for each friend so 12 * 5 = $60.00. Her initial reward was $5 and her friends made $60 for signing up and she received $60 when they signed up for a total of 5 + 60 + 60 = $125.00.
Thus, the answer is 125.
