Cara and her friends are still eating and hanging out with you at your taco food truck.

While eating, you and Cara catch up on her latest activities. She informs you that she recently got into live streaming and is loving it! After her first week, she had 10 subscribers. Then, a week later, she had 40% more subscribers.

Compute the week-2 total first: 10 + 0.4·10 = 10 + 4 = 14.
Then add 50% of that: 0.5·14 = 7.
So total = 14 + 7 = 21.

Answer: 21 subscribers.
