A bank features a savings account that has an annual percentage rate of r=5.2% with interest compounded quarterly. Marcus deposi
Aloiza [94]

Answer:

Part A)

P=\$8,500\\ r=0.052\\n=4  

Part B) S(7)=\$12,203.47  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

S(t)=P(1+\frac{r}{n})^{nt}  

where  

S is the Future Value  

P is the Present Value  

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

Part A)

in this problem we have  

P=\$8,500\\ r=5.2\%=5.2/100=0.052\\n=4  

Part B) How much money will Marcus have in the account in 7 years?

we have

t=7\ years\\ P=\$8,500\\ r=0.052\\n=4  

substitute in the formula above  

S(7)=8,500(1+\frac{0.052}{4})^{4*7}  

S(7)=8,500(1.013)^{28}  

S(7)=\$12,203.47
