Question

A store marked up the prices p of its merchandise by 11%. The marked-up prices of the merchandise can be written as 1.11p. Which other expression is this equal to?

Answer 1

111% of p

Explanation:

The new price is 11% higher than the original price "p", so we can affirm that the new price is the old price plus 11% of itself:

new price = p + 0.11p = (1 + 0.11)p = 1.11p

we can also say that the new price is 111% of p, as the old price is 100% of p, and we added 11% of p.
