Let's denote the sales for the previous Saturday as $x.

According to the problem, the sales for last Sunday were an increase of 6.5% over the sales for the previous Saturday.

So, we can set up the equation:

x + 6.5%x = $1,278

To solve this equation, we first convert the percentage to a decimal by dividing by 100:

x + 0.065x = $1,278

Combining like terms:

1.065x = $1,278

To isolate x, we divide both sides of the equation by 1.065:

x = 1278 / 1.065

Calculating this division:

x ≈ 1200

Therefore, Sally's sales for the previous Saturday were approximately $1,199.06.

Answer: 1200
