Original price is #$16#.

Explanation:

Since there is a #30%# depreciation, that means that #$11.20# is #100%-30%=70%# of the original price.

#100%# version of the value would be the original one, therefore, the original price would be #100/70# times more than the sale price.
#11.20 xx 100/70 = 16#
