Final answer:
The figurative language used in the sentence is hyperbole, an exaggerated statement used for emphasis.
Step-by-step explanation:
The type of figurative language in the sentence, "Even if Eleanor could avoid the bus today even if her fairy godmothers showed up with a pumpkin carriage, she’d still have to find a way to get back to school tomorrow morning," is a hyperbole.
A hyperbole is an exaggerated statement or claim not meant to be taken literally. It is used for the sake of emphasis or dramatic effect. Here, the idea of fairy godmothers showing up with a pumpkin carriage, like in Cinderella's story, is an exaggeration to emphasize the improbability of an easy solution to Eleanor's problem.
