Let Cellphone cost = 100n
then, 22.5% tax applicable on the sum in excess of $800
so, Tax = 22.5% of (100n-800)
Thus, Total cost ie, 934.75 = 100n + 22.5% of (100n-800)
934.75 = 100n + (9/40) of (100n-800)
934.75 = 122.5n +180
n = 1114.75 / 122.5
n = 9.1.........(1)
Thus, Tax = 22.5% of (100n-800)
= 22.5% of (910-800)..........using (1)
= (9/40) of 110
= 99/4
= 24.75
(C) is the CORRECT answer
