Astore had a sale on art supplies. the price
p of each item was marked down 60%.
which expression represents the new price?
a 0.4p c 1.4p
b 0.6p d 1.6p

The expression that marks the new price is choice A 0.4 p. Since we mark the prices down 60%, the customer will only be charged 40% of the p price which is 0.4 x p.  Think of a candy bar that originally costs $1 and is marked down 60% by a discount sale.  The new price is $0.40.  

100%-60%=40%=0.4
so new price is 0.4p
A=0.4p
