Hi All,

We're told that the normal price of a dress is D, but when on sale has its price reduced by 15% and the staff are allowed a further 10% reduction on the discounted price. We're asked for a staff member's price in terms of D. This question can be solved by TESTing VALUES.

IF....
D=$100
The discounted price = $100 - (.15)($100) = $100 - $15 = $85
The staff price = $85 - (.1)($85) = $85 - $8.50 = $76.50

Thus, the staff's price is (76.50/100)(D) = 0.765D

Final Answer: C
