3) A product is marked down 15%; the sale price is $127.46. What was the
original price?

elling price (S.P)  =  (100 - m)% ⋅ Original price (1)

Here,  

S.P  =  127.46,  m  =  15

Substitute 127.46 for S.P and 15 for m in (1).

127.46  =  (100 - 15)% ⋅ Original price

127.46  =  85% ⋅ Original price

127.46  =  0.85 ⋅ Original price

127.46 / 0.85  =  Original price

149.95  =  Original price

So, the original price is $ 149.95.
