SAT Question d1042cf8: Linear Equations In Two Variables answer and explanation with Desmos solution

Choice D is correct. It's given that the food truck buys forks for $$0.04$ each. Therefore, the cost, in dollars, of $x$ forks can be represented by the expression $0.04x$. It's also given that the food truck buys plates for $$0.48$ each. Therefore, the cost, in dollars, of $y$ plates can be represented by the expression $0.48y$. Since the total cost of $x$ forks and $y$ plates is $$661.76$, the equation $0.04x+0.48y=661.76$ represents this situation.
