Answer:
Step-by-step explanation:
5/8 +1/n = 7/8
1/n= -5/8 +7/8
1/n = 2/8
1/n= 1/2
then you would try to get n by itself
by dividing n/1 to 1/n and 1/2

Here is the answer if you can't read my writing than just ask. also if you have any questions about how I got something feel free to ask
Simplify both sides of the equation
Subtract 2 from both sides
Divide both sides by 5


OR

Given the marginal propensity to consume (MPC), the miltiplier is given by
Multiplier = 1 / (1 - MPC)
Given that the marginal propensity to consume is 0.8, the multiplier is given by
Multiplier = 1 / (1 - 0.8) = 1 / 0.2 = 5
