She can pay the loan 18 months.
Step-by-step explanation:
Given,
Tracie has to pay $ 25 each month to pay the loan.
She has $ 450 in her account to pay the loan.
To find the number of months she can pay the loan.
We will apply the unitary method.
$ 25 she can pay in 1 month
$ 1 she will pay in [tex]\frac{1}{25}[/tex] month
$ 450 she will pay in [tex]\frac{1}{25}[/tex] × 450 months.
= [tex]\frac{450}{25}[/tex]
= 18 months
