Money left
1 blouse -50
Or
1 pant - 15
Money left are same
Therefore, 1 blouse -50=1 pant -15
1 blouse - 1 pant = 50-15 = $35
1 blouse is $35 more than 1 pant
3 blouse = 3 pant + (3×35=105)
Given 3 blouses + 2 pants =425
3 pants +105 + 2 pants = 425
5 pants = 320
1 pant = 64
1 Blouse = 64+35 =$99
b) Total money = 425 + 99-35= $474.
