The marked up price of a dress set is $130. Calculate the price of the dress after a 6% sales tax is applied.

Answer: $137.8

Step-by-step explanation:

1. First we find the 6% of $130 by doing the following calculations:

6/100 * $130 = $7.8

2. Since the 6% is a sales tax, then we add the 6% value to the original cos value which is $130, to give:

$130 + $7.8 = $137.8

137.80
