See a solution process below:

First, we need to determine the total amount of products Elda purchased before taxes:

Two pairs of shoes at $50 each is: #2 xx $50 = $100#

Plus a dress at $30 is: #$100 + $30 = $130#

Plus a pair of trousers at $20 is: #$130 + $20 = $150#

We can now use this formula to find the total purchase prices, including the sales tax:

#p = c + (c * t)#

Where:

#p# is the total purchase price. What we are solving for.

#c# is the cost of the products. $150 for this problem.

#t# is the tax rate. 4 percent for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 4 percent can be written as #4/100#.

Substituting and solving for #p# gives:

#p = $150 + ($150 * 4/100)#

#p = $150 + ($600)/100#

#p = $150 + $6#

#p = $156#

Elda paid a total of $156.
