Answer:

Additional <u>$1,750 </u>must be invested by Ben.

Explanation:

Note: The question is not complete as some dots are omitted. The question is therefore given correctly before answering it as follows:

If Ben invests $3500 at 4% interest per year, how much additional money must he invest at 5 1/2 % annual interest to ensure that the interest he receives each year is 4 1/2 %.

The question is now answered as follows:

From the question, we have:

Initial amount invested = $3,500

Interest rate on initial amount invested = 4%, or 0.04

Interest amount from initial amount invested = Initial amount invested * Interest rate on initial amount invested = $3,500 * 4% = $140

Let y represents the additional amount to invest. Therefore, we have:

Interest rate of additional amount invested = 5 1/2% = 5.5% = 0.055

Interest amount from additional amount invested = y * Interest rate of additional amount invested = y * 0.055 = y0.055

Total interest amount = Interest amount from initial amount invested + Interest amount from additional amount invested = $140 + y0.055

New amount invested = Initial amount invested + y = $3,500 + y

Interest rate of new amount invested = 4 1/2% = 4.5% = 0.045

Interest amount from new amount invested = New amount invested * ($3,500 + y) * 0.045 = $157.50 + y0.045

Since total interest amount must equal interest amount from new amount invested, we equate the two and solve as follows:

Total interest amount = Interest amount from new amount invested

$140 + y0.055 = $157.50 + y0.045

We can now solve for y as follows:

y0.055 - y0.045 = $157.50 - $140

y0.01 = $17.50

y = 17.50 / 0.01

y = $1,750

Therefore, additional <u>$1,750 </u>must be invested by Ben.

Consider a small country that is closed to trade, so its net exports are equal to zero. The following equations describe the eco
inna [77]

Answer:

1. Aggregate output demanded is $500 billion. True.

Aggregate Demand (Y) = C + G + I

Y = 40+0.9∗DI + 80 + 20

Y = 40 + 0.9 ∗ (Y−100) + 80 + 20

Y = 50 + 0.9Y

0.1Y = 50

Y = $500 billion

2. Suppose the government decides to increase spending by $10 billion without raising taxes. Because the expenditure multiplier is 10. True.

Expenditure Multiplier = 1 / ( 1 - Marginal Propensity to Consume)

Marginal Propensity to Consume = 0.9 as per the Consumption function.

= 1/ ( 1 - 0.9)

= 10

2. b. this will increase the economy's aggregate output demanded by $100 billion. True.

Change in Aggregate output = Increase in government expenditure * expenditure multiplier

= 10 billion * 10

= $100 billion

3. ... In this case, the economy's aggregate output demanded is $500 billion . True.

Aggregate Demand (Y) = C + G + I

Y = 40+0.9∗DI + 80 + 20

Y = 40 + 0.9 ∗ (0.80∗Y) + 80 + 20

Y = 140 + 0.72Y

0.28Y = 140

Y = $500 billion

4. Given an income tax of 20%, the expenditure multiplier is approximately 3.6. True.

As a result of the new tax, the MPC will become;

= 0.9 * ( 0.80 * Y)

= 0.72Y.

Expenditure Multiplier = 1 / ( 1 - Marginal Propensity to Consume)

= 1/ ( 1 - 0.72)

= 3.57

= 3.6

4. b. Therefore, if the government decides to increase spending by $10 billion without raising tax rates, this would increase the economy's aggregate output demanded by approximately $36 billion. True.

Change in Aggregate output = Increase in government expenditure * expenditure multiplier

= 10 billion * 3.6

= $36 billion

5. A $10 billion increase in government purchases will have a larger effect on output under a fixed tax of $100 billion. True.

When the tax was fixed, an increase in Government purchases of $10 billion resulted in an increase in Aggregate output of $100 billion. When the Government switched to income taxes however, a $10 billion increase in Government spending led to a significantly lesser increase in Aggregate output of $36 billion.
