3x + 1 = (x-1)^2
3x + 1 = x^2 - 2x + 1
0 = x^2 -5x
0 = x(x-5)
x = 0,5

Answer: $9.81

Step-by-step explanation:

Here, Tiffany buys a basket of watermelons on sale for $9 before tax.

Therefore, Initial cost of a basket of watermelons = $9

And, he sales tax is 9%.

Therefore tax on a basket of watermelons,

9% of 9 = $\frac{9\times 9}{100} = 0.81$

But, The total cost of a basket of watermelons = initial cost + tax

= 9+0.81=9.81

Therefore, Tiffany pays $9.81 for the basket of watermelons.
