Distance formula: SR (A^2+B^2)
SR [(2+9i)^2 + (2-4i)^2] =
SR [4 + 18i + 81i^2 + 4 - 8i + 16i^2] =
SR [8 + 10i + 97i^2]

Fran deposited 4869 into a savings account that pays simple annual interest rate of 3.25% how much interest will she earn after
Whitepunk [10]

Answer:

$395.61

Step-by-step explanation:

The formula for simple interest is:

i=Prt

Where

i is the interest amount

P is the principal amount

r is the rate of interest per time period

t is the time period

Here,

P = 4869

we want to find after 30 months, that converted to years is:

30/12 = 2.5 years

t = 2.5

The annual rate is 3.25% = 0.0325

Now, substituting, we find our answer:

i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61

The interest earned is <u>$395.61</u>
