Akimi4 [234]

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
