Explanation:

Marginal Revenue Product (MRP) of a factor (here capital) is the change in firm's revenue, due to employing one additional unit of that factor.

It is calculated as : product of Marginal (additional) product from the factor (capital) , with marginal (additional) revenue of a product

MRPS (k) = MPP (k) x MR

Eg : If MPP of capital (k) = 5 , MR = 10 .

So, MRP (k) = 10 x 5 = 50

being born in poverty would limit the people's chances, opportunities and benefits.

this happen because of several things, such as:

- poor people tend to gain less access to good education and nutrition. this mean that their chance to obtain high paying jobs would also be limited.

- poor people tend to socialize with other poor people while the rich tend to socialize with other rich people. this means that simply throguh their social circle, rich people would have more business opportunities compared to the poor people.

- rich people tend to have more capital in their disposal. this would benefit them in business since it is far easier for them to fund their business operation compared to poor people.
