B) 21.11% increase
C) 11.11% increase
D) 21.11% decrease

Answer 1

Answer:

A) 11.11% decrease

Step-by-step explanation:

It is easier to take values instead of x and y in this type of questions/

Let initial per hour payment be 9 and working time be 9 hours. So income = 9x9 = 81.

Increase of per hour payment to 12 and decrease of 33.33% gives 6 hours.

Final income = 12x6 = 72.

% decrease = 9/81 x 100 = 11.11%
