Given:
Principal value = 40000
Rate of compounded interest = 20%
Time = 2 years
To find:
The interest.
Solution:
Formula for amount is

Where, P is principal, r is rate of interest and t is time in years.
Putting the given values, we get





Now, the formula for interest is



Therefore, the amount of compound interest is 17,600.
99/36= 11/4= 2.3 is my answer
Y=mx+b
m being the slope
b being the y intercept
y=-5/1x-5
simplified it would be
y=-5x-5
