A dress on sale in a shop is marked at $D. During the discount sale its price is reduced by 65%. Staff are allowed a further 60% reduction on the discounted price. If a staff member buys the dress what will she have to pay in terms of D ?
Choose the most appropriate option:
A) 0.15D  B) 0.16D  C) 0.65D  D) 0.14D  E) 0.05D
Effective discount = a + b + ab/100 = - 65 - 60 + (-65)(-60)/100 = -86   Sale price = 0.14D * ( 1 - 86/100)   Sale price = .14 * 0.14D   Answer (0.14D)
