First let's define the variables of the problem: t: Tip b: dinner bill. We write the inequality based on the following proposition: "Maria would like to leave a tip (t) of at least 15% of her dinner bill (b)" We have then that the inequation is: t> = 0.15b Answer: An inequality best could be used to find the amount of the tip Maria would like to leave is: t> = 0.15b
