For this case we must find the unit cost of the dresses Sara bought taking into account that I spend a total of $ 80.34. To do this, we must divide the total cost by 3.
Let the variable "x" be the unit cost for each dress.
[tex]x = \frac {80.34} {3}\\x = 26.78[/tex]
Thus, each dress cost Sara 26.78 $
