Answer:
$14.49

Since the question asked you how much you spent on the meal including the 5% tax and the 15% tip after the tax, it's basically asking you to calculate the percentage of the meal and subtracting it by the amount.
3/2x
-2y = -3x+18
y = 3/2x-9
100 adults and 200 children
$10 × 100 = $1000
$5 × 200= $1000
$1000 + $ 1000 = $ 2000
-x2+4=-x=4-2=2
-x=2
x= -2
