Unbiased

Step-by-step explanation:

Because in the dictionary it says showing no prejudice for or against something; impartial.  "his assessment of the benefits and drawbacks was unbiased." So when I read that, it was not prejudice, it was showing that whoever started the survey, was not prejudice, cus he was trying to help the company. Hope this helps you :)

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
