Given that Byron is conducting an experiment to determine whether a new medication is effective in reducing coughing. Byron finds 1200 volunteers with coughing issues and divides them into two groups.

This implies that medication has a positive effect of reducing coughing.
The merchandise is marked up 11%. This means you pay 100% of the price plus 11%. We can represent that as (1+r) where r is the percent marked above. For 11%, this expression would be 1+0.11. We multiply that by the price p. p(1+0.11). This simplifies to p+0.11p. We can further simplify it to 1.11p.
