The simple interest formula is:
Where
i is the interest accrued
p is the principal amount (loan amount)
r is the rate of interest, in decimal
t is the time
Now,
Given,
p = loan amount = 2500
r = 7/100 = 0.07
t = 4
Substituting into the formula, we can get the simple interest earned:
So, for 4 years, you have to pay an interest amounting $700.
Answer: $700
