Answer:
$38.1
Step-by-step explanation:
Tax: 30*0.07 = 2.1
Tip: 30*0.2 = 6
Total: 30 + 2.1 + 6 = 38.1
This answer is not confirmed to be correct:
$456 is the total amount so it would be on one side of the equal sign.
$456 = $75.00 + 9.50x.
I hope this helps!
X-6=0
Add +6 to both sides of the equation to get rid of -6 and leave x by its self.
X+1=0
Subtract -1 to both sides of the equation to get rid of +1 and leave x by its self.
Solution:
X= 6
X= -1
Hope this helped ;)
