Answer

Explanation:

Step1: Calculate marked - up price

The cost price is $255 and it is marked up 100%. The marked - up price is $255\times(1 + 100%)=255\times2 = 510$.

Step2: Calculate price with sales tax

The sales tax rate is 11%. The total price Cassie paid is $510\times(1 + 11%)=510\times1.11 = 566.1$.

Answer:

$566.1$
