To prove

As given

Kito makes on online purchase of a guitar case for $39.99, a tuner for $24.99 and picks for $26.99.

cost of all online purchase items = guitar case cost + tuner cost + picks cost

                                                      = $39.99 + $24.99 + $26.99

                                                      = $91.97

Taxes are 6% of the total purchase price.

6% is written in the decimal form.

= 0.06

Tax price = 0.06 × 91.97

                = $ 5.52 (Approx)

Total online purchase cost =  cost of all online purchase items + Tax price

                                            = $91.97 + $5.52

                                            =$ 97.49

As the shipping charges $8.20 from $50 up to $100 .

Total amount of kito billed = $ 97.49 + $8.20

                                            = $ 105.69

Therefore the option (a) is correct .

i.e Kito has been billed correctly.
