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%.

Answer:
3x -2y = -5
Step-by-step explanation:
Standard form is ...
ax +by = c
where the leading coefficient (a, or b if a=0) is positive and a, b, c are mutually prime.
Multiplying the equation by 2 gives ...
2y = 3x +5
We can subtract 2y+5 to get standard form:
3x -2y = -5
