Spent 23 minutes answering this question so please mark as the brainliest.

Step-by-step explanation:

Let value of car be 100

Then:

P= 100

R =12.5%

t = 3yrs

A= P(1-R/100)^T

=100(1-12.5/100)^3

=100(1-125/1000)^3

=100(1000-125/1000)^3

=100(875/1000)^3

=100*875/1000*875/1000*875/1000

=66.9921875

A=67

By profit loss method:

Loss(L)= P-A

=100-67

=33

Loss%=L/P*100

=33/100*100%

=33%
