Question 1

You open a new bank account by depositing $205. You then write checks for $37, $42, and $61, followed by a deposit of $58. What is your new balance?

Accepted Answer

To find the new balance, we must subtract the total amount of checks from the initial deposit and add any subsequent deposits.

$205 (initial deposit) - $37 (first check) - $42 (second check) - $61 (third check) + $58 (subsequent deposit) = $123.

Therefore, the new balance is $123. Choice (C) is the correct answer.

Question 2

Question 4

Multiply: 0(-12)

Accepted Answer

Any number multiplied by zero is zero. Therefore, 0(-12) equals 0.

Question 5

Perform the indicated operations: 12 - 5 - 11 + 3 - 5 - 9

Accepted Answer

The correct calculation is 12 - 5 - 11 + 3 - 5 - 9 = -15.

Question 6

Evaluate the following: (-17)(3)

Accepted Answer

The answer of Evaluate the following: (-17)(3)...

Question 7

Multiply: 7(-4)

Accepted Answer

When multiplying a positive number and a negative number, the result is always negative. Therefore, 7(-4) = -28. Choice C is the only answer option that represents a negative number.

Question 8

Sharon watched her stock for several days starting with a value of $25. If her stock rose $4, dropped $8, rose $11, dropped $6, rose $2, dropped $9, and rose $15, what was the value of her stock at the end of the 7 days?

Accepted Answer

We can keep a running total of the changes in the stock value: +4, -8, +11, -6, +2, -9, +15. Adding these up, we get a total change of +9. Starting with the initial value of $25, this gives a final value of $34. Therefore, the correct answer is (B).

Question 9

Multiply: -3(-9)

Accepted Answer

When you multiply two negative numbers, the result is positive. Therefore, -3 multiplied by -9 equals 27.

Question 10

Multiply: 4(-3)(-5)(2)

Accepted Answer

4(-3)(-5)(2) = -60(-6) = 360. Thus, the correct choice is C.

Question 11

Multiply: -28 · 0

Accepted Answer

Any number multiplied by 0 is always equal to 0. Therefore, the answer to -28 multiplied by 0 is 0.

Question 12

Evaluate the following: -2(-3)(-7)

Accepted Answer

The answer of Evaluate the following: -2(-3)(-7)...

Question 13

Multiply: 4(2)(-6)(2)

Accepted Answer

4(2)(-6)(2) can be simplified as:
4 * 2 * -6 * 2
= (4 * 2) * (-6 * 2)
= 8 * (-12)
= -96
Therefore, the correct answer is C.

Question 14

Multiply: 6(-3)(2)(0)(-4)(7)

Accepted Answer

The answer of Multiply: 6(-3)(2)(0)(-4)(7)...

Question 15

Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter. What was the net profit for the year?

Accepted Answer

The net profit for the year is calculated by adding the profits and subtracting the loss: $28,951,000 + $20,570,000 + $15,342,000 - $48,037,000 = $16,826,000.

Question 16

Evaluate the following: (-18)(3)

Accepted Answer

The answer of Evaluate the following: (-18)(3)...

Question 17

Evaluate the following: 4(-3)(3)

Accepted Answer

The answer of Evaluate the following: 4(-3)(3)...

Question 18

Evaluate the following: -2(-2)(5)

Accepted Answer

The answer of Evaluate the following: -2(-2)(5)...

Question 19

Evaluate: 12 - 7 + 8 - (-4)+ (-5)- 1

Accepted Answer

Following the order of operations (PEMDAS), we simplify the parentheses first:
12 - 7 + 8 - (-4) + (-5) - 1 = 
12 - 7 + 8 + 4 - 5 - 1 
Then, we can combine like terms:
12 + (8 + 4) + (-7 - 5) - 1 = 
12 + 12 - 12 - 1 = 
24 - 13 = 11
Therefore, the answer is D)11.
