if the marginal propensity to save is 0.12 the marginal propensity to consume(mpc) is the multiplier is

If the marginal propensity to save is 0.12, the marginal propensity to consume(mpc) is 0.88, and the multiplier is 8.33.

Explanation:

From the question, we are given the following:

mps = Marginal propensity to save = 0.12

The marginal propensity to consume (mpc) and the multiplier can therefore be calculated as follows:

mpc = 1 - mps (1)

Substituting the values for mps into equation (1), we have:

mpc = 1 - 0.12

mpc = 0.88

Also, we have:

Multiplier = 1 / mps (2)

Substituting the values for mps into equation (2), we have:

Multiplier = 1 / 0.12

Multiplier = 8.33

Therefore, if the marginal propensity to save is 0.12, the marginal propensity to consume(mpc) is 0.88, and the multiplier is 8.33.
