Should be Q, because it is more than 121, but less than 144. 121 is 9 away from 130, and 144 is 14 away. So, the answer would be
B) Q
The answer would be y=0.15x + 35 because 35 is like the base, the lowest he’ll pay, and then he’ll pay 0.15 which is 15% of the groups tips which is where the x comes in!
hope this helps!!

Adding all vakus in data set and divide by the number of values in the data set
