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?

Let's find the total cost before the tax and tip.

14+16+2*1.25+2*4.25 = $41

The tip is added before the tax so let's calculate it first.

1.15 * 41 = $47.15

Now add the 7% tax.

1.07 * 47.15 = $50.45
