Explanation
The movie theater offers a 30% discount on the regular price of $8.50. To calculate the discounted price, we multiply $8.50 by 0.30, which gives us $2.55. Then, we subtract $2.55 from $8.50 to get the discounted price of $5.95.

Explanation
The student estimated that she scored 700 on the math portion, but she actually scored 660. To find the percent error, we need to calculate the difference between the estimated score and the actual score, which is 700 - 660 = 40. Then, we divide this difference by the actual score (660) and multiply by 100 to get the percent error. So, (40/660) * 100 = 6.06, which is approximately 6.1%. Therefore, her percent error is 6.1%.

Explanation
AJ saved 20% by buying the TV on sale. To calculate the savings percentage, we need to find the difference between the regular price and the sale price, which is $1500 - $1200 = $300. Then, we divide this difference by the regular price ($300/$1500) and multiply by 100 to get the percentage. The result is 0.2, which is equivalent to 20%. Therefore, AJ saved 20% by purchasing the TV on sale.

Explanation
Ainsley spends $28 out of her $50 allowance each week at the local coffee shop. To find the percentage, divide $28 by $50 and multiply by 100. The calculation is (28/50) * 100 = 56%. Therefore, 56% of her allowance is spent at the coffee shop each week.

Explanation
The percent of tax applied to Morgan's purchase can be calculated by finding the difference between her total bill and the cost of the book, and then dividing that difference by the cost of the book. In this case, the difference is $13.92 - $12.95 = $0.97. Dividing $0.97 by $12.95 gives us approximately 0.075, which is equivalent to 7.5%. Therefore, the correct answer is 7.5%.

Explanation
To calculate the interest on a loan, you multiply the principal amount (in this case, $1000) by the interest rate (3%) and the time period (8 years).

So, the calculation would be:
Interest = $1000 * 0.03 * 8 = $240

Therefore, the correct answer is $240.

Explanation
After receiving a 25% discount, Ms. Ward will pay 75% of the original price. Therefore, she will pay 0.75 * $60 = $45. Then, she needs to add the 7% sales tax to this amount. The sales tax can be calculated as 7% of $45, which is 0.07 * $45 = $3.15. Adding this tax to the discounted price, Ms. Ward will actually spend $45 + $3.15 = $48.15 on the suit.

Explanation
Zach surveyed students at his school for a math project and found that 18% of those surveyed selected hamburgers as their favorite food. The question asks for an estimate of the total number of people Zach surveyed. Since 18% of the total is given as 38 people, we can set up a proportion to find the total number of people. If 18% is equal to 38, then 100% (the total) is equal to x. Solving this proportion, we find that x is approximately equal to 211. Therefore, Zach surveyed about 211 people.
