Michelle and Natalie both went out to eat at a new restaurant. Michelle’s bill was $22.50, and she left a 15% tip. Natalies bill was $24.25, and she left a 10% tip. Whose total bill was the greatest?

Michelles's total bill:
Total Bill = Pre-Tax Bill * (1 + tax rate)

Since 15% = 0.15, we have:
Total Bill = 22.50 * 1.15
Total Bill = 25.88

Natalie's total bill:
Total Bill = Pre-Tax Bill * (1 + tax rate)

Since 10% = 0.10, we have:
Total Bill = 24.25 * 1.10
Total Bill = 26.68

Natalie's total bill was the greatest.
