Question 1

If Edgar eats 8 2/3 doughnuts in a week and Ellen eats 4 ½ doughnuts in a week, how many more doughnuts will Edgar have eaten?

Accepted Answer

4 1/6

Answer

To find out how many more doughnuts Edgar ate, subtract Ellen's amount from Edgar's: 8 2/3 - 4 1/2. Convert these mixed numbers to improper fractions: 26/3 - 9/2. Find a common denominator, which is 6, making the fractions 52/6 - 27/6. Subtracting gives 25/6, which converts back to the mixed number 4 1/6.

Question 2

If Isaac scored 16 points in the first half of a basketball game and half as many in the second half, how many did he score in the game in all?

Accepted Answer

24

Answer

Isaac scored 16 points in the first half. In the second half, he scored half as many points, which is 16 / 2 = 8 points. To find his total score for the game, add the points from both halves: 16 + 8 = 24 points. Isaac scored 24 points in total.

Question 3

A shirt that was selling for $24 has had its price reduced by 15%. How much does it cost now?

Accepted Answer

$20.40

Answer

To find the new price, first calculate the amount of the discount. 15% of $24 is 0.15 * $24 = $3.60. Then, subtract the discount from the original price: $24 - $3.60 = $20.40. Alternatively, if the price is reduced by 15%, the new price is 85% of the original price, so 0.85 * $24 = $20.40.

Question 4

If the value of x is between 0.00776 and 0.0506, which of the following number could be x?

Accepted Answer

0.008

Answer

The value of x must be greater than 0.00776 and less than 0.0506. Let's evaluate the given options. 0.008 is indeed greater than 0.00776 and less than 0.0506, making it a possible value for x. The other options are either too large (0.890) or too small (0.0008).

Question 5

George buys 6 t-shirts for $5 each and 4 pairs of jeans for $8.50 each. He uses the following expression to calculate the total amount of money spent: 6 (5) + 4 (8.5). Which of the following expressions could George also have used?

Accepted Answer

4 (5 + 8.5) + 2 (5)

Answer

George's original expression is 6(5) + 4(8.5). We need to find an equivalent expression. Option B, 4(5 + 8.5) + 2(5), expands to 4(5) + 4(8.5) + 2(5). Combining the terms with 5, we get (4+2)(5) + 4(8.5), which simplifies to 6(5) + 4(8.5), matching the original expression.
