p + 0.11p

Step-by-step explanation:

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.

P (1+r) = p (1+0.11) = p+0.11p=1.11p
