⇒ 10\frac{1}{2}(\frac{1}{3})

⇒ \frac{20+1}{2}(\frac{1}{3})

⇒ \frac{21}{2}(\frac{1}{3})

⇒ \frac{3(7)}{2}(\frac{1}{3})

⇒ \frac{7}{2}

⇒ 3\frac{1}{2} pages

Holly wants to save money for an emergency. Holly invests 1,500 in an account that pays an interest rate of 6.75%. How many year
lina2011 [118]
The formula is
A=p (1+r)^t
A future value 7300
P present value 1500
R interest rate 0.0675
T time?
7300=1500 (1+0.0675)^t
Solve for t
Divide both sides by 1500
7300/1500=1.0675^t
Take the log for both sides
Log (7300/1500)=t×log (1.0675)
Divide both sides by log (1.0675)
T=log(7,300÷1,500)÷log(1.0675)
T=24.2 years round your answer to get 24 years

Hope it helps!
