Question 1: In the year 2020, Sarah earned a monthly salary of $48,200, with 14% of that amount being deducted for income taxes. Her monthly pay in 2025 was $51,800, with 16% of that amount being deducted for income taxes. What was her typical take-home income from 2020 to 21?
- $46,486
- $48,482
- $42,482 (Correct answer)
- $44.462
Correct answer: $42,482
The question asks for 'typical take-home income from 2020 to 21' but provides data for 2020 and 2025. Assuming the question intends to ask for the average take-home income between the two provided years, we calculate the take-home pay for each. In 2020, it was $48,200 * (1 - 0.14) = $41,452. In 2025, it was $51,800 * (1 - 0.16) = $43,512. The average of these two amounts is ($41,452 + $43,512) / 2 = $42,482.
Question 2: Solve the problems below: <br>
<br>
18 - 3 + (- 5) =
Correct answer: 10
To solve the expression 18 - 3 + (-5), we follow the order of operations from left to right. First, subtract 3 from 18, which gives 15. Then, add -5 to 15, which is equivalent to subtracting 5 from 15. This calculation results in 10.
Question 3: Peter rides the elevator up to the 10th floor starting from the ground floor. After that, Peter descends two stories and ascends eight. On what floor is Peter?
Correct answer: 16
Peter starts at the ground floor (0). He first ascends 10 floors, placing him on the 10th floor. Next, he descends two stories, bringing him to the 8th floor (10 - 2 = 8). Finally, he ascends eight more stories, which means he is on the 16th floor (8 + 8 = 16).
Question 4: In the nearby public schools, Officer Smith frequently serves as a drug-use prevention officer. He does three school visits per week for 40 weeks of the year. In a year, how many schools does he visit?
- 90
- 100
- 110
- 120 (Correct answer)
Correct answer: 120
To find the total number of school visits Officer Smith makes in a year, multiply the number of visits per week by the number of weeks he works. He makes 3 visits per week for 40 weeks. Therefore, 3 visits/week * 40 weeks/year = 120 visits per year.
Question 5: In order to make a withdrawal from her account, Amy visits her bank. She has $527.41 left over. She takes out $250.00. How much money still remains in her account after the withdrawal?
- $287.41
- $277.41 (Correct answer)
- $227.41
- $267.41
Correct answer: $277.41
To find out how much money remains in Amy's account, subtract the amount she withdrew from her initial balance. She started with $527.41 and withdrew $250.00. Therefore, $527.41 - $250.00 = $277.41 remains in her account after the withdrawal.
Question 6: A suspect in a robbery has been detained. The bond amount in this case has been imposed by the judge at $1 million. To issue a bail bond, the bail bondsman needs to have a 10% deposit. How much of the $1,000,000 must the robbery suspect pay to obtain the bail bond?
- $10,000
- $100
- $100,000 (Correct answer)
- $1,000
Correct answer: $100,000
To calculate the required deposit, find 10% of the total bond amount. The bond is $1,000,000, and the bail bondsman requires a 10% deposit. Therefore, 10% of $1,000,000 is calculated as 0.10 * $1,000,000, which equals $100,000.
Question 7: There has been a break-in at a nearby pharmacy. The types of pharmaceuticals that were taken, together with their total values, are listed as follows: narcotics ($7,000), barbiturates ($4,000), analgesics ($9,500), and other ($3,000). <br>
How much did the stolen products cost in total?
- $22,500.00
- $23,000.00
- $23,500.00 (Correct answer)
- $24,500.00
Correct answer: $23,500.00
To find the total cost of the stolen products, sum the values of each type of pharmaceutical listed. Add $7,000 (narcotics), $4,000 (barbiturates), $9,500 (analgesics), and $3,000 (other). The sum is $7,000 + $4,000 + $9,500 + $3,000 = $23,500.
