Don and Marie like to go to a good restaurant. Dinners are $16 to $19 dollars with soup or salad. A beverage is $1.50. Dessert is $3.75. If one dinner is $16, the other is $19 and each diner has a beverage and dessert, what will the cost be if a 6% tax is charged and a 15% tip on the pre-tax amount is left? $
