This is basic algebra. If 6.88 was spent on 2 paints, that means 1 paint set was 3.44. Since the price was reduced by 1.35 if we add 1.35 to 3.44, we get our answer: $4.79
Hint: Set up an equation because that helps. In this case, it's...
original price/2, +1.35 for old price, x is the old price
[tex]x=\frac{6.88}{2} +1.35[/tex]
