Let the money earned on Wednesday be x

Then, Money earned on Friday = x + 15

Abd, money earned on Saturday = 2x

Money earned on Sunday = $50

Total income = $345

So, x + x + 15 + 2x + 50 = 345

4x = 345 - 65

4x = 280

x = 280/4

x = 70

So, more money earned on Wednesday than Sunday = $(70 - 50)

= $20
