Answer:
the balance after 9 monthly payments is, $270
Step-by-step explanation:
Given the equation:
[tex]b = 540-30m[/tex] ....[1]
where,
b represents the balance in dollars that you owe on a drum set after m monthly payment.
We have to find the balance after 9 monthly payments
⇒ m = 9 months
Substitute the given values in [1] we have;
[tex]b = 540-30(9)[/tex]
⇒[tex]b = 540 -270 =270[/tex]
Therefore, the balance after 9 monthly payments is, $270
Balance after 9 monthly payments = $270
Word problem on linear equations
The balance owed after m monthly payments is given by the equation:
b = 540 - 30m
where m represents the number of months
b represents the balance after m months
To calculate the balance after 9 monthly payments, substitute m = 9 into the equation b = 540 - 30m
b = 540 - 30(9)
b = 540 - 270
b = 270 dollars
Balance after 9 monthly payments = $270
