David took his family out for dinner. He planned to leave a 20% gratuity on the bill. What is the total cost if the bill was $12
denis23 [38]
Let’s find 1% of 125 first.
125 x 0.01 = $1.25
1.25 x 20 = $25 gratuity.

Bill + gratuity = Total
$125 + $20 = $145

$145 is the answer.

Hope that helped! :)

b.) Probability of selecting three students and one faculty members from 20 students and 5 faculty volunteers = no of ways of selecting three students and one faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
