Answer :

40% of 195 is 78
195 x 0.40 = 78
Subtract $78 from $195
195 - 78 = 117
The discounted price of the boots is $117

$195  x  40%

195  x .40 = 78

The price decrease is $78.00

If you need to know the price of the boots after the discount just subtract

$195.00  -  78.00  = $117.00

Hope this helps. :)
