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?

Answer is $50.02.

Step-by-step explanation:

Dinners of Bob and Marie are = $14 + $16 = $30

Beverage costs  = 1.25 × 2 = $2.50

Dessert costs     = 4.25 × 2 = $8.50

Total = 30 + 2.50 + 8.50 = $41.00 (without tax)

Now we calculate 7% tax and 15% tip

Tax = 41 × 0.07 = $2.87

Tip  = 41 × 0.15  = $6.15

Now  add tax and tip in total amount

= 41 + 2.87 + 6.15 = 50.02

Dinner will cost $50.02.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
