Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Price of item 1 without GST = US$ 3.99

Price of item 2 without GST = US$ 58.99

Price of item 3 without GST = US$ 25.99

Goods and Services Tax = 10%

2. What is the total price after adding GST?

We will use the following formula to determine the total value of Ruby's purchase after adding GST, this way:

Total price after adding GST = Price of item 1 * 1.10 + Price of item 2 * 1.10 + Price of item 3 * 1.10

Total price after adding GST = 3.99 * 1.10 + 58.99 * 1.10 + 25.99 * 1.10

Total price after adding GST = 4.39 + 64.89 + 28.59 (Rounding to the next cent)

Total price after adding GST = US$ 97.87
