I might have a answer....
Answer:
Manuel Belgrano was a procer of Argentina.
He was a lawyer and participated in the May revolution and in the independence of Argentina against the Spanish.
In turn, I face great struggles together with Mariano Moreno and José de San Martín.
He was in charge of managing the troops of Northern Argentina where he fought right there and contributed to the liberation of Peru.
But one of the reasons that makes him most recognized is that he has always worked in the right to knowledge of the Argentine people, that is why he specialized in Europe and promoted the education of the country regarding his intellect.
Explanation:
Manuel Blegrano today is highly recognized in Argentina, respected as a procer, and most of his memories are respected in the Argentine national anthem and in the house of Tucuman that remains in the province of Tucuman, Argentina.
He was born in the province of Buenos Aires and was not only a lawyer as he was named, but also a military man, journalist, diplomat and economist.
The opportunity cost was: The money she would have earned working.
<h3><u>
Explanation:</u></h3>
When there exists two choices and you choose one, then the profit that you lose when selecting one choice over the other choice is called as the opportunity cost. Thus it helps in choosing a best decision where there are more alternatives are available.For instance consider you have 100$ and you decide to invest either in useful things or something that you enjoy.
In the example given, Sam is offered with an extra shift where she gets an extra pay. But she told to give that offer to some other person. Hence, the opportunity cost will be the amount that she might have earned when she accepted to work night.
