Answer:
Number of cheaper dresses sold  is 35
Number of expensive  dresses sold  is 15
Step-by-step explanation:
Given:
Cost of cheaper dresses = $90
Cost of  expensive dresses = $140
Total cost of  the dresses = $5250
To Find:
Number of cheaper dress = ?
Number of expensive  dress = ?
Solution:
Let 
The number of  cheaper dresses be x
The number of  expensive dresses be y
(Number of cheaper dresses X cost of cheap dress) +  (Number of Expensive dresses X cost of  expensive dress)  =  $5250
 =  $5250
=  $5250
It is given that the 20 more of the cheaper dresses than the expensive dresses is sold 
So, 
 number of cheaper dress  =  20  +  number of expensive dress
x = 20 + y---------------------------------------(1)







y = 15
Substituting y in (1)
x = 20 +15
x= 35
