You go out to dinner with 5 friends. The bill at the end of your meal is $168. If you want to leave an 18% tip, how much money should be left as a tip? You leave the tip on the table then pay the bill at the register. How much is paid at the register if there is 6% tax? How much money in total have you spent by the time you leave the restaurant?

Read below!!!     (>XD)

Step-by-step explanation:

168 x 0.18 = tip amount given = $30.24

168 x 0.06= tax

Even more simple method

168 x 1.06 = total including tax = 178.08

30.24+178.08=total paid for dinner including tax and tips

= 208.32

54 kilometers per hour

step-by-step explanation:

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
