SAT Question 4a090a46: Linear Inequalities answer and explanation with Desmos solution

Choice A is correct. It's given that Julissa already has $86$ hours of flight time. Let $x$ represent the number of additional hours of flight time Julissa needs to get her private pilot certification. After completing $x$ hours of flight time, Julissa will have completed a total of $86+x$ hours of flight time. It's given that Julissa needs at least $100$ hours of flight time to get her private pilot certification. Therefore, $86+x\ge 100$. Subtracting $86$ from both sides of this inequality yields $x\ge 14$. Thus, $14$ is the minimum number of additional hours of flight time Julissa needs to get her private pilot certification.
