how long Will it take for $7000 investment to grow to $7553 and the annual rate of 3.4% compounded quarterly assume that no withdrawals are made
Question
Answer:
Answer:[tex]t=2.25\ years[/tex] Step-by-step explanation:we know that The compound interest formula is equal to [tex]A=P(1+\frac{r}{n})^{nt}[/tex] 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 [tex]t=?\ years\\ P=\$7,000\\ r=0.034\\n=4\\A=\$7,553[/tex] substitute in the formula above [tex]7,553=7,000(1+\frac{0.034}{4})^{4t}[/tex] solve for t[tex](7,553/7,000)=(1.0085)^{4t}[/tex] [tex](1.079)=(1.0085)^{4t}[/tex] Applying log both sides[tex]log(1.079)=log[(1.0085)^{4t}][/tex] [tex]log(1.079)=(4t)log(1.0085)[/tex] [tex]t=log(1.079)=[(4)log(1.0085)][/tex] [tex]t=2.25\ years[/tex]
