If the consumption function is c = $200 billion + 0.5y, note: some values are in 'trillions' and others are in 'billions'. ( a. what is the mpc?

The marginal propensity to consume (MPC) in the given equation is 0.5.

The formula above is in slope intercept form. The MPC is like the slope of the equation. It gives the change in consumption, C, over the change in income, Y.

For example, if we let Y = 1, then the consumption will go from 200 to 200.5. It was a change of 0.5 over 1. Or just 0.5.

To solve the hypotenuse of a triangle, you need to use the Pythagorean Theorem.

The formula for the Pythagorean Theorem is a^2 +b^2 = c^2

a and b represents the two legs that are given to you.

c represents the hypotenuse of the triangle.

To find c you would solve a and b squared, then add them together, and then find the square root.
