To make a profit; to give s.o. a share of the profit for their work in selling s.t.; to make a profit off of s.o. (in a bad sense); to keep s.t. as a profit [-un].
I made three hundred pesos profit on those mangoes yesterday.
Give him one peso of the profit for each manggo so he will be willing to sell them.
If you are charging me a hundred pesos, it can only mean that you are making a profit off of me.
Keep the two pesos as a profit. Anyway he definitely won't be aware it.
