Explanation
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.

Explanation
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%.

Explanation
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.
