SAT Question dd875c97: Linear Inequalities answer and explanation with Desmos solution

Choice A is correct. It's given that a truck can haul a maximum of $5,630$ pounds. It's also given that during one trip, the truck will be used to haul a $190$ -pound piece of equipment as well as several crates. It follows that the truck can haul at most $5,630-190$, or $5,440$, pounds of crates. Since $x$ represents the number of $25$ -pound crates, the expression $25x$ represents the weight of the $25$ -pound crates. Since $y$ represents the number of $62$ -pound crates, $62y$ represents the weight of the $62$ -pound crates. Therefore, $25x+62y$ represents the total weight of the crates the truck can haul. Since the truck can haul at most $5,440$ pounds of crates, the total weight of the crates must be less than or equal to $5,440$ pounds, or $25x+62y\le 5,440$.
