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?

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
