The simple interest formula is I=Prt , where I is the interest, P is the principal, r is the interest rate, and t is the time.

DaniilM [7]

t = 5.3 years
(about 5 years 4 months)

Equation:
t = (1/r)(A/P - 1)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 7.2%/100 = 0.072 per year,
then, solving our equation

t = (1/0.072)((4835.6/3500) - 1) = 5.3
t = 5.3 years

$10,000+8.55 sales tax

Pavlova-9 [17]

Answer:

$10,008.55

Add 10000, and 8.55 to give the total.

10,000.00

The cents will be .55 since the $10,000 does not have any cents included.

The $8 will stay since the $10,000 does not have any dollars below 10 dollars.

So, the answer will be $10,008.55
