The simple interest formula is:
[tex]i=\text{prt}[/tex]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:
[tex]\begin{gathered} i=\text{prt} \\ i=2500\times0.07\times4 \\ i=700 \end{gathered}[/tex]So, for 4 years, you have to pay an interest amounting $700.
Answer: $700
