Answer:
b. [tex]y=2904-121x[/tex]
Step-by-step explanation:
Cost of the couch = $2904
Orlando will pay for 24 months = $121
The equation that Orlando can use to find out how much money he still owes after each month of the plan will be :
[tex]y=2904-121x[/tex]
Let us check this :
Let us take x = 1
[tex]y=2904-121[/tex] = $2783 left to pay
Let us take x = 2
[tex]y=2904-121(2)[/tex] = $2662 left to pay
Let us check x = 4
[tex]y=2904-121(4)[/tex] = $2420 left to pay
Therefore, option B is correct.
