Answer:
20%
Step-by-step explanation:
Given: Tip to waitress= $19
Total dinner bill= $95
Now, finding the percent of dinner bill did family leave for the tip.
Percent of tip= [tex]\frac{bill\ amount}{Total\ bill} \times 100[/tex]
⇒ Tip percentage= [tex]\frac{19}{95} \times 100= 0.2\times 100[/tex]
∴ Tip percentage= 20%
Hence, 20% of the dinner bill did family leave for the tip.
