A couple needs $55,000 as a down payment for a home. If they invest the $40,000 they have at 4% compounded quarterly, how long w

slava [35]

Answer:

8 years

Step-by-step explanation:

Compound interest formula

$A(t)= A_0(1+\frac{r}{n})^{nt}$

A(t) is the final amount 55000

A_0= 40000, r= 4% = 0.04, for quarterly n=4

$55000=40000(1+\frac{0.04}{4})^{4t}$

divide both sides by 40000

$1375=(1+\frac{0.04}{4})^{4t}$

$1375=(1.01)^{4t}$

Take ln on both sides

$ln(1375)=4tln(1.01)$

divide both sides by ln(1.01)

$\frac{ln 1375}{ln 1.01}=4t$

Divide both sides by 4

t=8.00108

So it takes 8 years
