With a principal investment of $19,200, which account will have the greatest value after 5 years? simple interest: I = P • r • t interest compounded annually is A = P (1 + r)t interest compounded quarterly: A = P (1 + )4t A. 3.6% with interest compounded annually B. 3.8% in a simple interest account C. 3.4% with interest compounded annually D. 3.2% with interest compounded quarterly

Answers

Answer 1
Answer: Given:
Principal: 19,200
term: 5 years

a) Interest compounded annually:
A = 19,200 (1 + 0.036)^5
A = 19,200 (1.036)^5
A = 19,200 (1.1934)
A = 22,913.28

b) Simple Interest
I = 19,200 * 0.038 * 5
I = 3,648.38

19,200 + 3,648.38 = 22,848.38

c) Interest compounded annually
A = 19,200 (1 + 0.034)^5
A = 19,200 (1.034)^5
A = 19,200 (1.182)
A = 22,694.40

d) Interest compounded quarterly
A = 19,200 (1 + 0.032/4)^4*5
A = 19,200 (1 + 0.008)^20
A = 19,200 (1.008)^20
A = 19,200 (1.173)
A = 22,521.60

Answers

x=total number of students.
80% of x=20
Therefore, the equaciton can be used to find the total number of students, in the math class is:
(80/100)x=20

We can solve this equation:
(80/100)x=20
x=(20*100)/80=25

Answer: the equation is (80/100)x=20 and its solutions is 25 students.

Answer:

The Answer is 25 students.

Answers

Answer:

If a point has these signs of coordinates: +,− then the point lies in the quadrant 4. If it is like 0,+, the point lies on the positive y axis. If it is like 0,−, the point lies on the negative y axis. If it is like +,0, the point lies on the positive x axis.

Every member of the family gives a gift to every other member of the family. There are ten members this year. If there are just 2 members exchanging gifts, how many gifts will be exchanged

Answers

The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.

You decide to put $2000 in a savings account to save for a $3000 down payment on a new car. If the account has an interest rate of 4% per year and is compounded monthly, how long does it take until you have $3000 without depositing any additional funds?

Answers

Answer:

t=10.2\ years      

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+(r)/(n))^(nt)  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=?\ years\nP=\$2,000\nA=\$3,000\n r=0.04\nn=12  

substitute in the formula above  

3,000=2,000(1+(0.04)/(12))^(12t)

1.5=((12.04)/(12)})^(12t)    

Applying log both sides

log(1.5)=log[((12.04)/(12)})^(12t)]

log(1.5)=(12t)log((12.04)/(12))

t=log(1.5)/[(12)log((12.04)/(12))]  

t=10.2\ years
