88% of what number is 66? A.
75


B.
58.08


C.
1.3


D.
0.75

Answers

Answer 1
Answer: let the unknown number be x 
88% * x= 66 (divide both sides by 88%)
x= 66/88%
x= 75
Therefore the answer is A) 75
Answer 2
Answer: if the unknown number be x, then 
88 multiply x is 66
then we need divide both sides by 88
x = 66 : 88
x = 0.75
Now we need 0.75 multiply 100(%) and we get 75
Therefore the answer is

A) 75

john invested $2000 that earn interest at 4% per annum compounded monthly. two year later the interest rate is 4.50% compounded quaterly. determine the accumulated value of investment two year after the change

Answers

Answer:

\$2,369.11  

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  

Part 1)

t=2\ years\n P=\$2,000\n r=0.04\nn=12  

substitute in the formula above

A=2,000(1+(0.04)/(12))^(12*2)  

A=2,000(1.0033)^(24)  

A=\$2,166.29  

Part 2)

t=2\ years\n P=\$2,166.29\n r=0.045\nn=4  

substitute in the formula above

A=2,166.29(1+(0.045)/(4))^(4*2)  

A=2,166.29(1.01125)^(8)  

A=\$2,369.11

The sum of A and B is 171 and their difference is 35. What are the numbers?

Answers

Answer:

103 and 68

Step-by-step explanation:

Given

A + B = 171

A - B = 35

Add the two expressions to eliminate B.

B + (-B) = B - B = 0

We have

2A = 206

Divide both sides by 2 to isolate A

2A/2 = 206/2

A = 103

Now substitute 103 for A in either expression to get B

Using the first expression , we have

A + B = 171

103 + B = 171

Subtract 103 from both sides

103 - 103 + B = 171 - 103

B = 68

The numbers are 103 and 68

Check

103 + 68 = 171

103 - 68 = 35

Answer:

103 and 68

Step-by-step explanation:

since the difference has to be 35 subtract 35 from 171 (equals 136) then divide it by 2, you get 68 which is your first number, then add 35 back and get 103 for the second number, I hope this helped
