C) 92.65%
To find the percent decrease in customers, we first need to find the difference in the number of customers between the two given hours.
Number of customers on Saturday from 6:00 p.m. to 7:00 p.m. = 68
Number of customers on Wednesday from 5:00 p.m. to 6:00 p.m. = 5
Difference in number of customers = 68 - 5 = 63
Next, we need to find the percent decrease in customers, which is given by:
(percent decrease) = (difference / original) x 100%
where "original" refers to the number of customers on Saturday from 6:00 p.m. to 7:00 p.m.
Plugging in the values, we get:
(percent decrease) = (63 / 68) x 100% ≈ 92.65%
Therefore, the percent decrease in customers from the given hour on Saturday to the given hour on Wednesday is approximately 92.65%.
