Highest age = 55
Range = 34
b

Median is middle
17 total people
Formula for median:
(n + 1)/2 = th
n is the total
17 + 1 is 18
18 halved is the 9th number
The 9th number is 46
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%
Total cost = price + tax
Tax = 7 1/4 % of price
Tax rate = [7 + 1/4] = 7.25 %
Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51
Total cost = $89.75 + $ 6.51 = $96.26
