Lison and her family went out to dinner to celebrate the end of the summer. Alison agreed to pay the tip from the money she earned from her summer job. The total cost of the meal was $50.00. Alison left $9.00 for the tip. What percent tip did Alison leave?

9x2 = 18, add the percent sign

the answer is 18%.

There is multiple ways to answer a problem like this, but I will show you one. First, you must see how many times the total number will go onto 100. In this case, our total number is 50. 50 times 2 is 100. Then, we multiply the number we are trying to make a percentage. That number is 9, because she gave 9 dollars. We must multiply 9 by the same number we did to 50. 9 times 2 is 18, therefore the answer is 18%.
