Problema Solution
The sale price of an item that is discounted 28% of its list price L.
Answer provided by our tutors
If the list price is L and the discount is 28% of L, then the discount is 0.28L.
The sale price is then the list price L minus the discount 0.28L.
So the sale price S is given by S = L - 0.28L = 0.72L.
