Answer: a. 2.90%
b. 2.81%
Explanation:
Nominal rate = 6%
Inflation rate = 3.1%
a. What is the approximate real rate of interest?
The approximate real rate of interest will be calculated as:
= Nominal rate - Inflation rate
= 6.0% - 3.1%
= 2.90%
b. What is the exact real rate?
Exact real rate will be calculated as:
= (nominal-inflation) / (1+inflation)
= (6.0% - 3.1%) / (1 + 3.1%)
= 2.9% / 1.031
= 2.81%
Answer:
B) 790-700r
Explanation:
Aggregate Expenditure is the expenditure by all the sectors of economy. By Households = Consumption (C), By Firms = Investment (I), By government = Govt spending (G) & tax leakages (T), By Rest world = Next Exports (NX).
Autonomous Expenditure is the level of expenditure in economy, which doesn't depend on level of Income = Y.
AE = C + I + G + NX
[500 + 0.8 (Y-150) - 300r] + [200 - 400r] + 200 + 10
500 + 0.8Y - 120 - 300r + 200 - 400r + 210
500 - 120 + 200 + 210 - 300r - 400r + 0.8y
790 - 700r + 0.8y
As, it can be seen that the part of AE = '790 - 700r', excluding '0.8y' : is not dependent on Income Y. So, it is Autonomous Expenditure
Answer: 26.5% increase
Explanation:
Current profit = Sales - Variable costs - fixed costs
= ((32.50 - 16.50) * 360 bears) - 1,420
= $4,340
Sales increase by 20% = 360 * ( 1 + 20%) = 432 bears
New profit;
= ((32.50 - 16.50) * 432 bears) - 1,420
= $5,492
Effect of sales increase = ( 5,492 - 4,340) / 4,340
= 26.5% increase
the answer is B, resolve conflicts peacefully
Answer:
Since Interest Rate and Period is not given; we would assume the spring term begins in 4 months and
Explanation:
First we will require to use the compound interest formula.
It is not mentioned the compounding period in the question. However, many of the bank accounts today offer monthly compounding, and this will be used as the basis.
i=interest rate=7.62% p.a => 7.62/12=0.635% per month
FV=PV(1+i)^n
FV=future value = 2200
PV=present value, to be found
i=interest rate per compounding period (month)=0.00635
n=number of periods=4
2200=PV(1+0.00635)^4
PV=2200/(1.00635^4)
PV=$2144.99
In case interest is not compounded, we could apply the simple interest formula:
FV=PV(1+ni)
PV=2200/(1+4*0.00635)
PV=$2145.504
