Let us assume the total amount of meal charge paid by Michael without tax = x
Then
Amount paid to the waiter by Michael = 15x/100
Sales tax paid by Michael = 5x/100
Now we get the equation as
x + (5x/100) + (15x/100) = 18
(100x + 5x + 15x)/100 = 18
120x/100 = 18
120x = 1800
x = 1800/120
= 180/12
= 15 dollars
So the amount paid by Michael for the meal before tax and tip is $15. I hope the procedure is clear enough for you to understand.
Answer:
4/3
Step-by-step explanation:
12x-9y=-9
9y=12x-(-9)
9y=12x+9
y=12/9x+9/9
y=4/3x+1
y=mx+b where m=slope and b=y-intercept,
so the slope is 4/3
