Janice is currently 4.
In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.
I hope this helps!
Explanation
![9-\sqrt[]{-64}](https://tex.z-dn.net/?f=9-%5Csqrt%5B%5D%7B-64%7D)
Step 1
Let's remember that
A complex number is an object of the form
where a and b are real numbers and
![\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20i%5E2%3D-1%20%5C%5C%20i%3D%5Csqrt%5B%5D%7B-1%7D%20%5Cend%7Bgathered%7D)
so
![\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%209-%5Csqrt%5B%5D%7B-64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%5Ccdot64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%7D%5Csqrt%5B%5D%7B64%7D%20%5C%5C%209-8%5Csqrt%5B%5D%7B-1%7D%20%5C%5C%209-8i%20%5Cend%7Bgathered%7D)
therefore, the answer is
I hope this helps you
Answer:
$8.50
Step-by-step explanation:
let the price before tax be $x
given that the sales tax rate is 4%, hence the amount she paid in taxes
= 4% of x
= (4/100)x
= 0.04x
We can now build an equation for what she paid:
Amount Paid = price before tax + amount paid in taxes
8.84 = x + 0.04x
8.84 = 1.04x (divide both sides by 1.04 and rearranging)
x = 8.84 / 1.04
x = $8.50
