18 is 45% of a number
18 is 45% of x
18 = 45% of x
18 = 0.45 * x
Now, to isolate x, you divide both sides of the equation by 0.45.
18 / 0.45 = 0.45*x /0.45
x = 40
So, 18 is 45% of 40. Hope this helps! :)

Answer:
3rd option
Step-by-step explanation:
3(x + 8) - 9x = 6(4 - x) ← distribute parenthesis on both sides
3x + 24 - 9x = 24 - 6x , collect like terms on left side )
24 - 6x = 24 - 6x
Since both sides are the same then any value of x will make the equation true.
That is all real numbers are solutions

Step-by-step explanation:
the constant of proportionality is the cost divided by number of patrons
$49.96 ÷ 4 = $12.49
$74.94 ÷ 6 = $12.49
