How much money will be in a bank account for three years if $4 is deposited at an interest rate of 5% and the interest is compounded annually

Problem

You deposit $4 into a bank account paying 5% simple interest per month. You left the money in for 3 years. Find the interest earned and the amount at the end of those 3 years?

Result

The interest is $7.2 and the amount is $11.2.

Explanation

STEP 1: Convert interest rate of 5% per month into rate per year.

STEP 2: Find an interest by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this examplee P = $4, i = 60% and t = 3 years, so

STEP 3: Find an amount by using the formula A=P+I.

Since P = $4 and I = $7.2 we have

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
