2. To write the decimal 0.063 as a percent, multiply by 100. The result is 6.3%. Therefore, the answer is 6.30%.
3. To find the percent of students who live with their parents, divide 386 by 1,112 and multiply by 100. The result is approximately 34.71%. Therefore, the answer is 34.71%.
4. To write the percent 96.55% as a decimal, divide by 100. The result is 0.9655. Therefore, the answer is 0.9655.
5. To estimate each person's contribution to the total tip, multiply the total bill by the tip percentage (15%) and divide by 8 (Eryn and seven friends). The result is approximately $2.70. Therefore, the answer is $2.70.
6. To find 31% of 71, multiply 31% by 71. The result is approximately 22.01. Therefore, the answer is 22.01.
7. To find what percent 39 is of 156, divide 39 by 156 and multiply by 100. The result is 25%. Therefore, the answer is 25%.
8. To find the number of students in the entire class, divide 20 by 80% (or 0.80). The result is 25. Therefore, the answer is 25.
9a. To find how many goals Michelle made, multiply 70% by 130. The result is 91 goals. Therefore, the answer is 91 goals.
9b. To find what percent of the team's made goals Michelle made, divide 91 (goals Michelle made) by 456 (total team goals) and multiply by 100. The result is approximately 19.96%. Therefore, the answer is 19.96%.

14. To find the percent of markup, subtract the cost price ($319.85) from the selling price ($412.99). Divide the difference by the cost price and multiply by 100. The result is approximately 29%. Therefore, the answer is 29%.
15. To compare the sale prices, subtract the discount percentage (10% and 15%) from 100% to get the actual percentage paid. Multiply the regular price by the actual percentage paid. Store A sells the video game for $53.99, and Store B sells it for $55.24. Therefore, the answer is Store A; Store A’s sale price is $53.99, and Store B’s sale price is $55.24.
