Basically, you are asked to make an equation to represent the sales price after 6 months. But first, let's formulate the general equation. Let S be the sales price after t months, while P is the base price. The equation would be

S = P (1-0.05t)

Simplifying,

S = 0.95Pt

So, after 6 months, the sales price would be:

S₆ = 0.95P (6)

S₆ = 5.7P
