The loan repayment is an illustration of a linear function.
He will finish paying the loan after 6 months.
A linear function is illustrated as: [tex]\mathbf{y = mx + b}[/tex]
In this case:
Because the amount reduces after each monthly payment, the value of m will be taken as: m = -325
So, we have:
[tex]\mathbf{y = -325x +1950}[/tex]
When he finishes paying the loan, we have: y = 0.
So, the equation becomes
[tex]\mathbf{0 = -325x +1950}[/tex]
Add 325x to both sides
[tex]\mathbf{325x =1950}[/tex]
Divide both sides by 325
[tex]\mathbf{x =6}[/tex]
Hence, he will finish paying the loan after 6 months.
