If you are paid $23.25 per hour, what is your annual salary? (Assume you work 40 hours each week of the year.)

Answers

$23.25 per hour
work 40 hours per week
Find your annual Salary
In a month, there are approximately 4 or 5 weeks  (only refer to regular working days)
Let’s only use 4.
=> 40 x 4
=>160 hours in 1 month
In a years there are 12months
=> 12 x 4
=> 48 weeks in a years (only for regular working days) or let’s round it to 50 weeks per year
Now, let’s multiply 48 weeks by 40 hours and 50 by 40 hours
=> 48 x 40
=> 1920 hours in a year
=> 50 x 40
=> 2000 hours
Now, let’s  find how much is your annual salary
=> 1920 x 23.25 = $44 640
=> 2000 x 23.25 =$46500
=>approximate  or around

How can you tell if a number is divisible by 3? A. The last number is 3.   B. The sum of the digits of the number is a multiple of 3.   C. The first two digits are divisible by 3.   D. The number ends in an odd digit.

Answers

The correct answer is B. Try it out with the following number: 312, 1893, 255, 344, 232. Two of the or not divisible by 3 by the way.
B is correct. Also, if you have a number such as 876543 and add the digits, it is 33. If you did not know this was divisible by three, you could add 3+3 and get 6, which is divisible by three, making 876543 divisible by three.
