 You make your Actor rental with **7-day free trial** and then **$30/month**. During the first calendar month, three users start to use your Actor:
 
-- **User 1** (paid plan): Starts free trial on the 15th
-- **User 2** (paid plan): Starts free trial on the 25th  
-- **User 3** (free plan): Starts free trial on the 20th
+- _User 1 (paid plan)_: Starts free trial on the 15th
+- _User 2 (paid plan)_: Starts free trial on the 25th  
+- _User 3 (free plan)_: Starts free trial on the 20th
 
 The first user pays their first rent 7 days after the free trial, i.e., on the 22nd of the month. The second user only starts paying the rent next month. The third user is on the Apify free plan, so after the free trial ends on the 27th of the month, they are not charged and cannot use the Actor further until they get a paid plan.
 
 Your profit is computed only from the first user, since they are the only one who paid during this month. The revenue breakdown is:
 
-- **Total revenue**: $30 (from User 1 only)
-- **Your profit**: 80% of revenue = 0.8 × $30 = **$24**
+- _Total revenue_: $30 (from User 1 only)
+- _Your profit_: 80% of revenue = 0.8 × $30 = $24
