Answer and Explanation:

The costs of the slave trade were very low compared to the profits that this activity provided. The African slave trade started because the work in the European colonies needed a labor that was extremely cheap, but supported by the church of the time. In this case, the purchase of African slaves was the best option, as the Europeans paid about £3 for each slave and placed them in a precarious situation, of extreme poverty and lack of structure, while they worked hard on the farms that profited rivers of money for European crowns.

In this context, gains justified, expenditures and established the origins of capitalist society.
