Answer: the number of new light bulbs that they put in is 36

Step-by-step explanation:

How long will it take for $2500 to double if it is invested at 6% annual interest compounded 6 times a year? Enter exact calcula
12345 [234]

Answer:

Part 1) t=11.610\ years

Part 2) t=11.552\ years

Step-by-step explanation:

Part 1) 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  

A=\$5,000\\P=\$2,500\\ r=6\%=6/100=0.06\\n=6  

substitute in the formula above

5,000=2,500(1+\frac{0.06}{6})^{6t}  

2=(1.01)^{6t}  

Apply log both sides

log(2)=log[(1.01)^{6t}]

log(2)=(6t)log(1.01)  

solve for t

t=log(2)/[6log(1.01)]  

t=11.610\ years

Part 2) we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

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  

e is the mathematical constant number

we have  

A=\$5,000\\P=\$2,500\\ r=6\%=6/100=0.06  

substitute in the formula above

5,000=2,500(e)^{0.06t}

2=(e)^{0.06t}  

Apply ln both sides

ln(2)=ln[(e)^{0.06t}]

ln(2)=(0.06t)ln(e)

ln(2)=(0.06t)

t=ln(2)/(0.06)

t=11.552\ years
