SAT Question 520c8177: Linear Functions answer and explanation with Desmos solution

Choice D is correct. It's given that a veterinarian recommends that each day the rabbit should eat $25$ calories per pound of the rabbit's weight, plus an additional $11$ calories. If the rabbit's weight is $x$ pounds, then multiplying $25$ calories per pound by the rabbit's weight, $x$ pounds, yields $25x$ calories. Adding the additional $11$ calories that the rabbit should eat each day yields $25x+11$ calories. It's given that $c$ is the total number of calories the veterinarian recommends the rabbit should eat each day if the rabbit's weight is $x$ pounds. Therefore, this situation can be represented by the equation $c=25x+11$.
