A: the discounted cost is 80% of 750. That's 0.8*750=600. Because when the price is discount 20%, that means 20% is taken off. So 80% remains.

b: the profit is 792-600=192. This is 192/600*100= 32% profit.

c: she took 20% of the price off. If this means that she took $117 off, then the original price was 117/0.2=$585

d: She purchased it for $(468/1.3) = $360.
explanation: let the original price = x
We know that 468 = x + 0.3x = 1.3x
So, x = 468/1.3=360
