Question

Maria would like to leave a tip (t) of at least 15% of her dinner bill (b). Which inequality best could be used to find the amount of the tip Maria would like to leave?

Answer 1

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
