Justin and four friends went to dinner and a movie in Moscow, Russia where sales tax is 5.1%. Since it is illegal to pay with U. S. dollars or Euro, they paid in Russian Rouble (₽). For dinner, the young men each had the “Early-Bird Buffet” for 1300 ₽. Justin paid the entire bill (with sales tax) and tipped the waitress the standard 12% of the total bill. When the young men got to the theater, each bought a ticket for 300 ₽ and the “Big Man Snack” box for 155 ₽. Dusty had Reese’s pieces for 30.15 ₽. Sven decided to have nachos for 23.25 ₽, plus he paid the entire bill (with sales tax) since he had a “15% off total” coupon. At the end of the evening, the friends decide to split the entire cost evenly before they reimburse Justin and Sven.
