Answer:
for the first one its I=38.40 for the 2nd one its $315
Step-by-step explanation:
Simple interest , I, is calculated by multiplying the principal, P, by the rate,r, by the time, t, in years:
I = P * r * t
Here, P = $640
r = 0.03 (decimal value for 3%)
t = 2 years
The interest will be:
I = P * r * t
I = 640 * 0.03 * 2
I = $38.40
2nd one:
We know, Interest value = P * R * T /100
Here, P = 1500
R = 4.25
T = 4
Substitute their values,
I = 1500 * 5.25 * 4 / 100
I = 31500 / 100
I = 315
In short, Your Final Answer would be $315
3rd answer:
assuming you subtract 2% of 580 a month for six months. your remaining money would be $510.40
because you subtract $69.6 from 580
4th answer:
$1231
Step-by-step explanation:
Given,
Principal amount = $1200
Rate of interest = 3.9%
Time = 8 months or (8/12) 0.666667 years
Formula of simple interest =
A = 1200(1+(0.039 × 0.666667))
A = 1200 (1+0.026)
A = 1200 (1.026)
A = $1231
