Pretty sure the answer is A
Answer:1: no 2: They probably measured the speed and they added up all the points they got and divided it by the total number of points and it ended up with the mean, and average speed for the rider
Step-by-step explanation:
let cat food = x
total plus 5% = 105% = 1.05
1.05 * (11.50 + X) = 16.80
12.075 + 1.05x = 16.80
1.05x = 16.80-12.075
1.05x = 4.725
x = 4.725 / 1.05
x= 4.50
the cat food cost $4.50
11.50 +4.50 = 16.00
16.00 * 0.05 = 0.80
16.00 + 0.80 = 16.80
