#write a function total_price that has two parameters, list of prices and tax
#function returns total price based on the following discount rule:
#prices <=100 got 10% discount, prices>100 got 15% discount
#tax applied AFTER discount

#write a function random_list_float(size, min, max) that generates list of 
#size floating point numbers between min and max and returns the list

#write main that fist generates size of list, then calls function 
#random_list_float to generate the list of prices, assuming prices are between 
#75 and 125. Use function total_price to find the total

#example: 4 prices: 99.99 101 76.99 124.99, tax=7%
#find total price
