What letter grade is 34 over 50?

User Avatar

Asked by Wiki User

You can find the percentage by dividing 50 (the total) by the number you received (34).

That's a 68 percent. If your teacher grades on a curve, that could be anything from a D- to an A; on a strict percentage scale, it would normally be a D or D+ though a very lenient teacher might regard it as a C-.

Why a production possibility is concave?

User Avatar

Asked by Wiki User

A production possibility curve is concave because of the law of diminishing returns. As more resources are allocated to one good over the other, the opportunity cost increases, which leads to decreasing marginal rates of substitution. This results in a concave curve that shows the trade-off between producing different goods.
