Let the amount that the manufacturer gets per chocolate be C. The supermarket marks up the price by 3% and it is sold at $3.

So, we have C *( 1 + 3%) = 3

=> C* (1 + 0.03) = 3

=> C*( 1.03) = 3

=> C = 3/1.03

=> C = $2.91

The manufacturer gets $2.91 per chocolate.

Sorry not $2.1 but $2.91, but using the other way I just gave.

Why can't we just subtract 3% from 3 or 9 cents and we get $2.1
