SAT Question 3dffe9d2: Linear Functions answer and explanation with Desmos solution

Choice B is correct. It’s given that Josie purchased a pass to tour a nature preserve and $10$ identical stickers for $$62.00$ total. It's also given that the pass cost $$19.50$. Let $x$ represent the cost, in dollars, of one sticker. This relationship can be represented by the equation $19.50+10x=62$. Subtracting $19.50$ from both sides of this equation yields $10x=42.50$. Dividing both sides of this equation by $10$ yields $x=4.25$. Therefore, the cost of one sticker was $$4.25$.
