The given options represent different values for PI. Among these options, 3.14 is the most commonly known and widely used approximation for the mathematical constant PI. It is often used in various mathematical calculations and formulas, such as those involving circles and trigonometry. Therefore, 3.14 is the correct answer in this context.

The given question asks to subtract 1,583 from 1,600. When we subtract 1,583 from 1,600, we get the difference of 17. Therefore, the correct answer is 17.

The given expression is adding 2 dollars, 40 cents, and 2 quarters. To calculate this, we convert the quarters to their equivalent value in dollars, which is 50 cents each. So, 2 quarters equal 1 dollar. Then, we add the 2 dollars, 40 cents, and 1 dollar together, which gives us a total of $2.90.

The correct answer is $37,500 because to calculate 3% of $1,250,000, we multiply $1,250,000 by 0.03. This gives us $37,500.

The given equation 50/125 can be simplified by dividing both numerator and denominator by 25. This gives us 2/5. To convert this fraction to a percentage, we multiply by 100. Therefore, 2/5 is equal to 40%.

The correct answer is $34.74. To find the final price after tax and discount, we first calculate the tax amount by multiplying the original price ($36.00) by 7% (0.07), which gives $2.52. Then, we subtract the discount amount, which is 15% of the original price ($36.00 x 15% = $5.40). Subtracting $5.40 from the original price ($36.00 - $5.40 = $30.60), we then add the tax amount ($30.60 + $2.52 = $33.12). Therefore, the final price after tax and discount is $34.74.
