Find the time required for an investment of $3000 to grow to $9000 at an interest rate of 6.5% per year, compounded quarterly. (
Vanyuwa [196]

Answer:

t=17.04\ years

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{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  

P=\$3,000\\A=\$9,000\\ r=6.5\%=6.5/100=0.065\\n=4  

substitute in the formula above

9,000=3,000(1+\frac{0.065}{4})^{4t}  

solve for t

Simplify

3=(1.01625)^{4t}  

Apply log both sides

log(3)=log[(1.01625)^{4t}]  

Apply property of logarithms

log(3)=(4t)log(1.01625)  

t=log(3)/[4log(1.01625)]  

t=17.04\ years

The equation would be
g + (g + 9) = 45
2g + 9 = 45
- 9
2g = 36
÷ 2
g = 18
18 + 9 = 27
Girls: 18
Boys: 27
