Hey 17% discount on a watch saved a shopper $51. Find the price of the watch before the discount

To rephrase the question,

17% of what is $51?

Let me give you a short way or formula.

is/of = %/100

is = 51

0f = x

% = 17%

51/x = 17/100

51*100 = x*17

5100 = 17x

5100/17 = x

so x = 300

Discount = 17%=51 $ (given)

Let the price be=x

So formula is

Discount%/100 * actual price = discount (in$)

17/100*x=51

X=51*100/17

X=300$

Hence the price of the watch is 300$
