Cost of the spa treatment = $42
Percentage of sales tax = 6%
Percentage of tips = 20%
Normally the tips amount is calculated before adding sales tax.
Then
Amount of tips given = (20/100) * 42
= (1/5) * 42
= 8.40 dollars
Amount of sales tax taken = (6/100) * 42
= 252/100
= 2.52 dollars
Then
The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars
= 52.92 dollars
So we can see that $52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.
Answer:
A)
Step-by-step explanation:
negative number must be placed in parenthesis to avoid confusion.
W^2 - v + 1 Is represented as (-2)^2 - (-8) + 1
In general, for these kinds of problems, repeatedly subtract 360 degrees until you get something that lies between 0 and 360 degrees, since two coterminal angles will always differ by some multiple of 360 degrees.
In this case, our desired angle is 495-360=135 degrees.
We can write this expression as 10 - 4 = 9 - x
10 - 4 = 9 - x
6 = 9 - x
6 - 9 = 9 - x - 9
-3 = -x
-3/-1 = -x/-1
3 = x
