Question

The equation b=540−30m gives the balance b (in dollars) that you owe on a drum set after m monthly payments. What is the balance after 9 monthly payments?

Answer 1

B=540 - 30(9)

b=540 - 270

b = 270

$270

Answer 2

Answer:

the balance after 9 monthly payments is, $270

Step-by-step explanation:

Given the equation:

$b = 540-30m$              ....[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;

$b = 540-30(9)$

⇒$b = 540 -270 =270$

Therefore, the balance after 9 monthly payments is, $270
