Answer:
$25.5.
Step-by-step explanation:
We have been given that Aubrey's dinner cost $85. She tips the waitstaff 30% for excellent service.
To find the tip given to waitstaff by Aubrey we will find 30% of 85.
[tex]\text{Tip given by Aubrey to waitstaff}=85\times\frac{30}{100}[/tex]
[tex]\text{Tip given by Aubrey to waitstaff}=85\times 0.30[/tex]
[tex]\text{Tip given by Aubrey to waitstaff}=25.5[/tex]
Therefore, Aubrey gave $25.5 as tip to the waitstaff for their excellent service.
