You order an appetizer for $9.99, 2 entrées for $7.99 each, and a dessert for $3.49. the sales tax is 6% and you leave a 15% tip based on the bill with sales tax. what is the total cost of your restaurant outing

$35.65

Step-by-step explanation:

Given : The cost of an appetizer= $9.99

The cost of each entrees = $7.99

Then , the cost of 2 entrees =

The cost of a desert =$3.49

Now, the total cost of food you order =        (1)

Then, sales tax percent = 6% =0.06

Then, the sales tax amount =     (2)

The percent of tip = 15% = 0.15

Then , the tip amount:    (3)

Then , the total cost of your restaurant outing will be (adding (1), (2) and (3)) :-

Hence, the total cost of your restaurant outing = $35.65

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
