Answer:
She gave the tip of $ 25.50 to the waitstaff.
Step-by-step explanation:
Given,
The cost of dinner = $ 85,
Also, the percentage of tip she gave = 30%,
Hence, the amount of the tip she paid = 30% of the cost of dinner
= 30% of 85
[tex]=\frac{30\times 85}{100}[/tex]
[tex]=\frac{2550}{100}[/tex]
[tex]=\$ 25.50[/tex]
