Abank features a savings account that has an annual percentage rate of r=5.2% with interest compounded quarterly. marcus deposits $8,500 into the account.
the account balance can be modeled by the exponential formula s(t)=p(1+rn)^nt, where s is the future value, p is the present value, r is the annual percentage rate written as a decimal, n is the number of times each year that the interest is compounded, and t is the time in years.
(a) what values should be used for p, r, and n?
p= , r= , n=
(b) how much money will marcus have in the account in 7 years?
answer = $ .

Part A)

Part B)  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

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  

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

we have

substitute in the formula above  

answer: your gay

you dont know math

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
