Which of the following expressions represent 15% tip on a $20 meal? Which represents the total bill? **Select all that apply**.

kifflom [539]

Answer:

15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.

18 is 45% of what number? ____<br> Please help me I can't solve this

Alexxx [7]

18/x = 45/100

cross multiply

18/x * 45/100

45x =1800

divide both sides by 45

45x/45 =1800/45

x=40

18 is 45% of 40
