P= Price
O= Original price
N= Number of days
P= O - (N * 0.02)
EXAMPLE:
O= 50
N= 1 day
P= 50 - ( 1* 0.02) = 49.98
N= 2 days
P= 50 - ( 2* 0.02) = 49.96
N= 3 days
P= 50 - ( 3* 0.02) = 49.94
N= 4 days
P= 50 - ( 4* 0.02) = 49.92
N= 5 days
P= 50 - ( 5* 0.02) = 49.90
N= 6 days
P= 50 - ( 6* 0.02) = 49.88
N= 7 days
P= 50 - ( 7* 0.02) = 49.86
