23.75 + [ (0.18) (23.75) ]

Step-by-step explanation:

Ellen plans to leave an 18% tip with her $23.75 lunch bill.

Therefore, to determine her total bill, she use the expression

= 23.75 + (18% of 23.75)

= 23.75 + (0.18 * 23.75)

or 23.75 + [ (0.18) (23.75) ]

So the expression is 23.75 + [ (0.18) (23.75) ] to determine her total bill.
