Algebra / Linear functions Difficulty: Easy

A veterinarian recommends that each day a certain rabbit should eat $25$ calories per pound of the rabbit’s weight, plus an additional $11$ calories. Which equation represents this situation, where $c$ is the total number of calories the veterinarian recommends the rabbit should eat each day if the rabbit’s weight is $x$ pounds?

$c equals 25 x$

$c equals 36 x$

$c = 11 x + 25$

$c = 25 x + 11$

Explanation

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 $25 x$ calories. Adding the additional $11$ calories that the rabbit should eat each day yields $25 x plus 11$ 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 $c = 25 x + 11$ .

Choice A is incorrect. This equation represents a situation where a veterinarian recommends that each day the rabbit should eat $25$ calories per pound of the rabbit’s weight.

Choice B is incorrect. This equation represents a situation where a veterinarian recommends that each day the rabbit should eat $25 plus 11$ , or $36$ , calories per pound of the rabbit’s weight.

Choice C is incorrect. This equation represents a situation where a veterinarian recommends that each day the rabbit should eat $11$ calories per pound of the rabbit’s weight, plus an additional $25$ calories.
