Bob and marie like to go to a good steakhouse. dinners are $14 to $16 dollars with soup or salad. a beverage is $1.25. dessert is $4.25. if one dinner is $14, the other is $16 and each diner has a beverage and dessert, what will the cost be if a 7% tax is charged and a 15% tip on the pre-tax amount is left?
