A typical tip in a restaurant is 18% of the bill. If the bill is 150,what would the typical tip be​
Natasha_Volkova [10]

<u><em>You want to leave a 18% tip on a meal that cost $150.</em></u>

<u><em>First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.</em></u>

<u><em>Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or</em></u>

<u><em></em></u>

<u><em>0.18 x $150.00=$27.00.</em></u>

<u><em>So, the amount of tip you are going to leave is $27.00.</em></u>

<u><em></em></u>

<u><em>This makes the total cost of your meal (to write on your charge slip or other payment)</em></u>

<u><em></em></u>

<u><em>$150.00 + $27.00 = $177.00. </em></u>
