Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
It should be $92.00
80 • .15 = 12
so 15% of the total ($80) is 12.
add the 12 to the total 80+12= $92

Step-by-step explanation:
Tan can be defined as: 
as it simplifies to opposite/adjacent. If you know a bit about the unit circle, you'll know that the x-coordinate is going to be cos(theta) and the y-coordinate is going to be sin(theta). Since the sin(theta) is defined as opposite/hypotenuse, and the hypotenuse = 1, so sin(theta) is defined as the opposite side, which is the y-axis. Same thing goes for cos(theta), except the adjacent side is the x-axis.
Using this we can define tan
