Answer :
Answer:
[tex]T=52.5 \approx 53 months[/tex]
Step-by-step explanation:
From the question we are told that:
Annual income [tex]I=65000[/tex]
Annual tax [tex]T=65000-58000[/tex]
[tex]T=7000[/tex]
Student loan [tex]X=21000[/tex]
Payment budget [tex]Y=400[/tex]
Generally the Time taken to pay off is mathematically given by
[tex]T=\frac{Payment}{rate\ of\ payment }[/tex]
[tex]T=\frac{x}{\frac{x}{t}}[/tex]
[tex]T=x*\frac{t}{x}[/tex]
Therefore time taken
[tex]T=\frac{21000}{400}[/tex]
[tex]T=52.5 \approx 53 months[/tex]
