Final answer:
The given equation t=10m+40 indicates that for each month Chad subscribes to the streaming channel, his total cost increases by $10, so the correct answer is C.
Step-by-step explanation:
The correct answer to the question is C. The total cost will increase by $10 for every month that passes. This is evidenced by the equation t = 10m + 40, which models the scenario where t is the total cost and m is the number of months.
The membership fee is a one-time annual charge of $40, and the streaming channel subscription costs $10 each month. Thus, for each additional month Chad subscribes, he will pay an extra $10, resulting in an increase in the total cost of $10 per month.
The given scenario can be modeled by the equation t = 10m + 40, where t represents the total cost and m represents the number of months.
Looking at the equation, we can see that the coefficient of m is 10, which means that for every month that passes, the total cost will increase by $10. Additionally, the constant term in the equation is 40, indicating that there is an initial cost of $40 regardless of the number of months.
Therefore, the correct answer is D. The total cost will increase by $40 for every month that passes.
