Answer: she will owe $67.5 in 3 months.
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount owed.
R represents interest rate on over due accounts.
T represents the duration in years.
From the information given
P = 1500
R = 18%
T = 3 months = 3/12 = 0.25 year
I = (1500 × 18 × 0.25)/100 = $67.5
