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?

Accepted Answer

$42,482

Answer

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

18 - 3 + (- 5) =

Accepted Answer

10

Answer

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?

Accepted Answer

16

Answer

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?

Accepted Answer

120

Answer

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.

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?

Accepted Answer

$277.41

Answer

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.
