Tyler‘s orders a meal that cost $15 and the tax rate is 6.6% how much Will the sales tax Be on Tyler‘s meal Tyler also wants to leave a tip for the server how much do you think you should pay in all.

$18.39

Step-by-step explanation:

.066 x 15 = .99

15 + .99 = 15.99 (sales tax and meal)

Since he wants to leave a tip, average is 15%.

15.99 x .15 = 2.40

15.99 + 2.40 = $18.39

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
