Airline B ‘s average rating for convenience was approximately what percent greater than Airline A ‘s average rating for convenience?

A) 30%

B) 36%

C) 40%

D) 57%

E) 64%


Company B's average was 8.0
Company A's average was 5.1

8.0/5.1 = 1.57

1.57 is the fractional form of 157% so 8.0 is 157% of 5.1. 8.0 hence is 57% greater than 5.1

Because you cannot subtract 5.1 - 8.0 that is a negative number. You subtract A from B: B - A = 8 - 5.1. And A is 5.1.

In a survey, 100 travel agents each ranked Airlines A, B, and C in order of preference. Each of the 100 travel agents also rated the three airlines in five categories on a scale of 1 through 10, with 10 being the best rating.

Airline B ‘s average rating for convenience was approximately what percent greater than Airline A ‘s average rating for convenience?

A) 30%

B) 36%

C) 40%

D) 57%

E) 64%



Solution:

We can use the percent change formula to determine Airline B’s average rating for convenience was approximately what percent greater than Airline A’s average rating for convenience:

(8 - 5.1)/5.1 x 100 = 2.9/5.1 x 100 ≈ 57%
