Answer:

$18.15

Step-by-step explanation:

The total sales tax chargeable is:

$4.6+3.65=8.25\%$

We can now find the total amounts in taxes by multiplying the total tax rate by the pre-tax price,$220:

$Tax \ Amount= Item \ Price \ \times \ Tax \ Rate\\\\=\frac{8.25}{100}\times 220\\\\=18.15$

Hence, the total tax amount paid by Yuki is $18.15

Answer:

x = 23; not extraneous

Step-by-step explanation:

A solution is extraneous if it does not satisfy the original equation. Extraneous solutions can sometimes be introduced in the process of solving radical and rational function equations.

<h3>Solution</h3>

Squaring both sides of the given equation, we get ...

√(3x +12) = 9

3x +12 = 81 . . . . . . square both sides

x +4 = 27 . . . . . . . divide by 3

x = 23 . . . . . . . . . . subtract 4

<h3>Check</h3>

There is only one solution, and it satisfies the equation:

√(3×23 +12) = √81 = 9

The solution x = 23 is not extraneous.
