9. To determine how many shots Diane made, you can multiply the total number of shots she took (134) by the percentage she made (56%).

a. 134 shots * 56% = 75.04 shots (rounded to 75 shots)

So, Diane made approximately 75 shots.

b. To find the percentage of the team's made shots that Diane made, you can divide the number of shots she made (75) by the total number of shots made by the team (498), and then multiply by 100.

b. (75 shots / 498 shots) * 100 = 15.06% (rounded to 15.1%)

Therefore, Diane made approximately 15.1% of the team's made shots.

10. To calculate what percent of 25 is 10, you can divide 10 by 25 and multiply by 100.

10 / 25 * 100 = 0.4 * 100 = 40%

Therefore, 10 is 40% of 25.

11. To find the tax paid for a pair of earrings with a list price of $77, you can multiply the list price by the tax rate of 6.3%.

A: $77 * 6.3% = $4.851 (rounded to $4.85)

So, the tax paid for the pair of earrings is approximately $4.85.

B: To find the total cost of the pair of earrings, you can add the list price and the tax paid.

B: $77 + $4.851 = $81.850 (rounded to $81.85)

Therefore, the total cost of the pair of earrings is approximately $81.85.

12. To find Doug's sales for a week when he earned $555, you need to subtract his fixed rate of $75 from the total amount he earned and divide the remainder by 15% to find the sales.

$555 - $75 = $480 (remaining amount after deducting fixed rate)

$480 / 15% = $480 / 0.15 = $3200

Therefore, Doug's sales for that week were $3200.

13. To find the percent of change in the enrolled students at Arlington Country Day School from 2000 to 2010, you can subtract the number of students in 2010 (705) from the number of students in 2000 (823), divide the result by the number of students in 2000, and then multiply by 100.

Percent Change = (823 - 705) / 823 * 100

Percent Change = 118 / 823 * 100

Percent Change = 14.3% (rounded)

Since the number of students decreased from 2000 to 2010, the percent of change is a decrease. Therefore, the answer is 14.3% decrease.

14. To find the percent of markup, you can subtract the cost of the stereo from the selling price, divide the result by the cost, and then multiply by 100.

Percent Markup = (($181.99 - $102.30) / $102.30) * 100

Percent Markup = ($79.69 / $102.30) * 100

Percent Markup = 0.7785 * 100

Percent Markup = 77.85% (rounded to 78%)

Therefore, the percent of markup is approximately 78%.

15. To determine which store sells the book for the lower sale price, you can calculate the sale price for each store.

Store A:

Discount = 15% of $24.99
Sale Price = $24.99 - (15% * $24.99)
Sale Price = $24.99 - $3.74985 (rounded to $3.75)
Sale Price = $21.24

Store B:

Discount = 25% of $27.99
Sale Price = $27.99 - (25% * $27.99)
Sale Price = $27.99 - $6.9975 (rounded to $7.00)
Sale Price = $20.99

Therefore, Store B sells the book for the lower sale price ($20.99).

16. To calculate the final balance in an account with $840 invested at 4% annual simple interest for three years, you can multiply the initial balance by the interest rate and the number of years, and then add the result to the initial balance.

Final Balance = $840 + ($840 * 4% * 3 years)

Final Balance = $840 + ($840 * 0.04 * 3)

Final Balance = $840 + ($100.80)

Final Balance = $940.80

Therefore, the final balance is $918.40.
