I rated robbyegos answer bad because he just copied philos answer. That is rude. You did not deserve 2 points.

1. p% = p/100, so D. $pq/100
2. 89.5/69.5 = 1.28777, so 28.78% increase
3. 1722 = 100%P - 18%P = 82%P, so
P = 1722/0.82 = $2100

1. D)
2. gain = 89.50 - 69.50= 20.00
% gain = 20/69.50 (100) = 28.77%
3. 1722 = Price(1 - .18)
Price = 1722/0.82 = 2100.00
