Make them into improper fractions
(5*5)+3
(2*3)+2

Final fractions
28/5+8/3
Find a common denominator
Multiply 28/5 by 3
84/15
Multiply 8/3 by 5
40/15

Add - 84+40=124

I would rewrite them:
5 3/5 is the same as 18/5
2 2/3 is the same as 8/3

To add them you get the same denominator by multiplying the first fraction by 3 and the second by 5 for a denominator of 15

54/15+40/15
=94/15 or 6 4/15

Hope this helps!

Option D

Step-by-step explanation:

The objective of the survey is to assess the satisfaction level of the customers.

Out of the options given, option D is the closest to be used as a basis for gauging the satisfaction level of customers. Option A is irrelevant to the subject under discussion, as it is bears no semblance to the topic.

Option B also has this same tendency, and tend to view the satisfaction from the customers annual income, and not from the firm or its products. Using this definitely could give a measurement error.

Option C talks on inability of the user/customer of the media player to set the time. This failure is borne by the user, and not an inherent fault in the media player. As such, using this as a basis could lead to a measurement error.

Option D is the most suited for the survey.
