According to Okun's law, if the unemployment rate goes from 7% to 4%, what will be the effect on the GDP?
A. It will increase by 9%.
B. It will increase by 3%.
C. It will decrease by 9%.
D. It will decrease by 3%.

The correct answer is B. According to Okun's law, if the unemployment rate goes from 7% to 4%, the GDP will increase by 3%.

Step-by-step explanation:

Okun's Law establishes a direct relationship between unemployment and the production of a nation. Thus, the higher the unemployment, the lower the production, and on the contrary, the more the unemployment falls, the inversely proportional will be the increase in the country's production.

Thus, if the unemployment rate falls from 7% to 4%, that is, it decreases by 3%, the country's GDP will increase by 3%.

f

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
