Consider the following combinations of guns and butter that can be produced 0 guns, 20,000 units of butter, 5,000 guns, 15,000 units of butter, 10,000 guns, 10,000 units of butter, 15,000 guns, 5,000 units of butter 20,000 guns, 0 units of butter. the ppf between guns and butter is a a downward-sloping bowed-out curve b a downward-sloping straight line c an upward-sloping straight line d it is impossible to answer this question without knowing which good would be plotted on the vertical axis

B. Downward sloping straight line.

Explanation:

Production Possibility Frontier is graphical representation of two goods that an economy can produce , given resources & technology .

Production Possibility Frontier is downward sloping because of negative relationship between two goods , one good can be increased by reducing other - given same resources & technology.

The slope of PPF depends on Marginal Opportunity Cost i.e amount of a good sacrifised to gain an additional of the other one i.e Δgood sacrifised / Δgood gained . If MOC is constant : PPF is a straight line (like in this case) ; If MOC is increasing (general case - due to resource shift from efficient to inefficient good production) : PPF is concave / outward bowed curve ; If MOC is decreasing : PPF is convex .

As per given schedule :

Guns  Butter  MOC (Δgood sacrifised / Δgood gained)

0         20000    _

5000   15000    5000 / 5000 = 1

10000  10000   5000 / 5000 = 1

15000   5000    5000 / 5000 = 1

2000      0         5000 / 5000 = 1

As it can be seen : Guns are increasing & Butter are falling , so these have inverse relationship & PPF is downward sloping .The ratio of butter sacrifised to gain guns is constant, so MOC is constant & PPF is straight line.

odd consecutive integers are odd integers that follow each other. they have a difference of 2 between every two numbers. if n is an odd integer, then n, n+2, n+4 and n+6 will be odd consecutive integers. the first number in the pattern is always the variable on its own or in this case, "n". examples.
