Answer:
C. y = 11000(1.086)^7
Explanation:
Given the following data;
Principal = $11,000
Interest rate = 8.6% = 8.6/100 = 0.086
Time = 7 years
To derive a mathematical expression, we would use the compound interest formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
t is the number of years for the compound interest.
Substituting into the formula, we have;
A = $19,580
Answer:
a
Explanation:
because it makes sense in the sentence
Answer: Quarterly
Explanation:
Annual interest rate = 4.00%
Effective annual rate = 4.08%
To know if the bank is compounding interest daily or quarterly goes thus:
Effective Annual rate can be calculated using:
= (1+Periodic rate)^number of compounding periods - 1
Therefore, we calculate the daily compounding effective annual rate which will be:
= (1+4%/365)^365 - 1
= (1 + 0.04365)^365 - 1
= 4.08%
For Quarterly EAR, this will be:
= (1+4%/4)^4 - 1
= (1 + 0.04/4)^4 - 1
= 4.06%
Therefore, the a bank is compounding interest Quarterly
Answer: 0.70; 0.30
Explanation:
Marginal propensity to consume(MPC) is the additional spending by an economic agent due to a rise in income while the marginal propensity to save is the additional saving by someone due to rise in income.
Increase in income = $3,000
Increase in spending = $2,100
Increase in savings = $3,000 - $2,100 = $900
MPC = $2,100/$3,000
= 0.70
MPS = $900/$3,000
= 0.30
