What is 20% tip on a bill of $33

The tip amount will be $6.60 for a grand total of $39.60.

Step-by-step explanation:

1. You can easily determine 10% by moving the decimal place right by one. $33.00 -> $3.30; this is 10%

2. Multiply by two (2) to change the percentage from 10% to 20%; $3.30 * 2 = $6.60

3. To determine complete amount, add the original amount: $33.00 + $6.60 = $39.60.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
