Answer:
$ 27.09
Step-by-step explanation:
Given,
The regular price of the watch = $ 32.25,
The marked off percentage or discount percentage, in the sale = 16%,
So, the amount of marked off = 16% of regular price
= 16% of 32.25
= 0.16 × 32.25
= $ 5.16
Hence, the the price of the watch during the sale = Regular price - marked off
= $ 32.25 - $ 5.16
= $ 27.09
Last option is correct.

Answer:
Step-by-step explanation:
To prove: The sum of a rational number and an irrational number is an irrational number.
Proof: Assume that a + b = x and that x is rational.
Then b = x – a = x + (–a).
Now, x + (–a) is rational because addition of two rational numbers is rational (Additivity property).
However, it was stated that b is an irrational number. This is a contradiction.
Therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number.
Hence, the sum of a rational number and an irrational number is irrational.
