Ruffa received a 20% commission for every item, which she sold for $75 each. If she sold 124 items, how much was her commission?

Calculate commission per item:
Commission per item = 75 * 20%
Commission per item = 75 * 0.2
Commission per item = 15

Now, calculate total commission for 124 items:
Commission for 124 items = Commission per item * 124
Commission for 124 items = 15 * 124
Commission for 124 items = 1,860
