let's say the bill without the tip is "x" amount, so that'd be the 100% of the bill, but we also know that 4.50 is the 18% of "x".
so if 4.50 is the 18% of "x", how much is "x"?

Answer:
Step-by-step explanation:
so we are gonna have a percent decrease because it went from 188 to 42
decrease = (original number - new number) / (original number ) * 100
= (188 - 42) / (188) * 100
= (146 / 188) * 100
= 0.7766 * 100
= 77.66% decrease....not sure if u need ur answer rounded to the nearest percent or not....if so, its a 78% decrease
