Answer:
The correct answer is a. $2275.28; b. 17.04 years
Step-by-step explanation:
Principal to be invested is $2000
Interest rate (r) per year is 6.5 quarterly.
Interest is calculated compoundly.
a. Time (t) for the investment is given to be 2 years.
Amount after two years is = Principal ×
where the value of n is 4.
⇒ A = 2000 × 
⇒ A = $2275.28.
b. Now the value of A is given to be triple the principal = $ (3 × 2000).
Therefore we need to find the value of t.
⇒ 3 × 2000 = 2000 × 
⇒ ㏑ 3 = 4t × ㏑ ( 1.01625)
⇒ t = 17.04
Therefore it would take 17.04 years for the principal to triple.

Hi friend
#24
y/9+5=0
Simplify to both sides
1/9 y+5=0
Now subtract 5 from both sides
1/9 y+5-5=0-5
1/9 y=-5
Multiply both sides by 9 so we can find the y value
9(1/9 y)= (9)(-5)
y=-45
The answer is A ( Your answer was not good)
#25
3b-7<32
First you need to add 7 to both sides
3b-7+7=32+7
3b<39
Now divide both sides by 3 so we can find the value for b
3b/3<39/3
b<13
The answer is A
#26
3p-16<20
Now we gonna do the same thing
Add 16 to both sides
3p-16+16<20+16
3p<36
Now divide both sides by 3
3p/3<36/3
p<12
The answer is C
#27
3p-6>21
Just do the same thing
Add 6 to both sides
3p-6+6>21+6
3p>27
Divide both sides by 3
3p/3>27/3
p>9
The answer is B
I really hope that's help and good luck :0
