Question 205197
Let's make the price before the discount 1.00
With the 20% discount it sells for 1.00*.20=.80
On the .80 there is a 20% profit. Therefore .8*.2=.16 is profit. And .80-.16=.64 is the cost.
With the original price of 1.00 less the cost of .64 the profit is .36
.36/1.00=36% gross profit
