Answer:

a pair of trousers cost = x = 195 $

one shirt costs = x - 50 = 145 $

Step-by-step explanation:

  • let the cost of trouser be x.
  • cost of shirt = (x - 50)

  • 2 pairs of trousers cost = 2x
  • 3 shirts cost = 3(x - 50)

= 3x- 150

2 trousers and 3 shirts cost = 825

=> 2x + 3x - 150 = 825

=> 5x = 975

x = 195

a pair of trousers cost = x = 195 $

a pair of trousers cost = x = 195 $ one shirt costs = x - 50 = 145 $
