Step-by-step explanation:
Answer:
\text{Compounded Quarterly:}
Compounded Quarterly:
A=P\left(1+\frac{r}{n}\right)^{nt}
A=P(1+
n
r
)
nt
Compound interest formula
P=3500\hspace{35px}r=0.035\hspace{35px}t=19\hspace{35px}n=4
P=3500r=0.035t=19n=4
Given values
A=3500\left(1+\frac{0.035}{4}\right)^{4(19)}
A=3500(1+
4
0.035
)
4(19)
Plug in values
A=3500(1.00875)^{76}
A=3500(1.00875)
76
Simplify
A=6786.05963486
A=6786.05963486
Use calculator
A\approx 6800
<h2>A≈6800</h2>
