Answer:
$2.50
Step-by-step explanation:
The information is somewhat incomplete. It does not state whether simple or compound interest which could make a difference
I am assuming simple interest
The formula for simple interest is
I = Prt
where I is interest
P is amount of loan
r is annual rate of interest expressed as a decimal
t = number of years
We are given
P = $100
r = 10$ = 10/100 = 0.10
t = 3 months = 3/12 year = 1/4 th of a year
I = 100 x 0.10 x 1/4 = $2.50
