Step-by-step explanation:

3bc−4ad+6ac−2bd

Do the grouping 3bc−4ad+6ac−2bd=(6ac−4ad)+(3bc−2bd), and factor out 2a in the first and b in the second group.

2a(3c−2d)+b(3c−2d)

Factor out common term 3c−2d by using distributive property.

According to Okun's law, if the unemployment rate goes from 5% to 3%, what will be the effect on the GDP?

olga2289 [7]

Answer:

D. It will increase by 1%.

Step-by-step explanation:

Given

$u_1 = 5\%$ --- initial rate

$u_2 = 3\%$ --- final rate

Required

The effect on the GDP

To calculate this, we make use of:

$\frac{\triangle Y}{Y} = u_1 - 2\triangle u$

This gives:

$\frac{\triangle Y}{Y} = 5\% - 2(5\% - 3\%)$

$\frac{\triangle Y}{Y} = 5\% - 2(2\%)$

$\frac{\triangle Y}{Y} = 5\% - 4\%$

$\frac{\triangle Y}{Y} = 1\%$

This implies that the GDP will increase by 1%
