SAT Question 935f3403: Linear Equations In One Variable answer and explanation with Desmos solution

Choice B is correct. For a restaurant owner to purchase a pizza oven at a total price of $13,000$ dollars, a onetime down payment is required, and then fixed monthly payments are made for the remaining amount owed for the pizza oven. It’s given that the equation $13,000=2,800+200t$ represents this situation, where $t$ is the number of fixed monthly payments that are made. In this equation, $2,800$ is a constant term, which represents the onetime down payment, in dollars, and $200$ is the coefficient of $t$. Multiplying $200$ by $t$ gives the total amount, in dollars, paid by the fixed monthly payments. Therefore, the best interpretation of $200$ in this context is the amount, in dollars, of each fixed monthly payment.
