Answer:
- 10 percent interest due in one year
Step-by-step explanation:
Simple interest calculates interests using the formula below.
I= p x r x t
Where P = principal amount
r = interest rate
t= time in years
A). p= $5000, r= 7% or 0.07, t= 2 years
I = $5000 x 0.07 x 2
I = $5000 x 0.14
I= $700
B). p= $5000, r= 10% or 0.10 , t= 1
I = $5000 x 0.10 x 1
I= $500
c). P= $5000, r= 8% or 0.08, t= 18months or 1.5years
I= $5000 x 0.08 x 1.5
I=$400x 1.5
I=$600
Option B is the better deal. The interest amount is $500, which is the lowest amongst all the options.
