Question

Julissa needs at least 100 hours of flight time to get her private pilot certifiion. If Julissa already has 86 hours of flight time, what is the minimum number of additional hours of flight time Julissa needs to get her private pilot certifiion?

Accepted Answer

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 certifiion. 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 certifiion. 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 certifiion. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect. This is the number of hours of flight time Julissa already has, rather than the minimum number of additional hours of flight time Julissa needs. Choice D is incorrect. This is the number of hours of flight time Julissa will have if she completes 100 more hours of flight time, rather than the minimum number of additional hours of flight time Julissa needs.
