Let the number of hours Penny works at X be a
Let the number of hours Penny works at Y be b

Statement 1

$36 at X, $29 at Y..

But we don't know the hours she worked. We cannot calculate the total money earned.
Insufficient

Statement 2

a + b = 60
But we don't know the payment per hour hour. We cannot calculate the total money earned.
Insufficient

Statement 1+2

36a + 29(60-a) = 36a - 29a + (36*29)

We don't know a. Insufficient

Answer = E

Penny could be working in some other companies than X and Y. Hence A & B are not together suff let alone one at a time.
Answer E

VERITAS PREP OFFICIAL SOLUTION:

Question Type: What Is the Value?  This question asks you for a specific number indicating the amount of money that Penny earned during week W.

Given information from the question stem: Penny is paid hourly and works part time, and has two different employers, Company X and Company Y. Therefore, her total weekly pay will be (Hours Worked at X)(Pay Rate at X) + (Hours Worked at Y)(Pay Rate at Y).

Statement 1 : This statement provides the hourly rates for her work for the two companies, X and Y. However it does not provide a total number of hours worked for either company. This is not sufficient. Answers A and D are eliminated.

Statement 2 : Penny worked 60 hours total during week W. This means that she worked 60 hours for X and Y combined. However, nothing is indicated as to the rate that she was paid for this work. This statement is not sufficient and answer B is eliminated.

Together : Taken together, you have the total number of hours worked and the hourly rate for each of the two companies. Yet, it is not possible to know how to divide the 60 hours between X and Y. Since she is paid a different amount by each of the two companies it is necessary to know precisely how many hours she worked for each. Therefore, the statements together are still not sufficient.

The correct answer is E.
