William's family spent $100 for dinner. They paid 10% sales tax. Then they tipped the server 20% on the total (dinner + tax). How much did they spend on dinner, tax, and tip? Show your work.

99.9

Step-by-step explanation:

Okay, so we know that Willam's fam spend $100 dollars (without tax).

10% into a decimal is 0.1.

100+0.1= 100.1

When they tipped the server 20% of the total they took away 20% from the 100.1.

20% into a decimal is 0.2

If im not incorrect the anwser is 99.9

Please check this anwser as I might be incorrect. Thanks:)

$132

Step-by-step explanation:

100 * 1.1 (tax) * 1.2 (tip) = 132

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

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 %
