Michelle purchases a pair of jeans for $35 and a dress for $47. The store charges 8% sales tax on all purchases. How much will Michelle need to pay for her purchase, including tax?

Michelle needs to pay $88.56 to pay for her purchase, including tax.

Step-by-step explanation:

The purchasing cost of a pair of jeans = $35

The purchasing cost of dress = $47

The total purchase cost = $35 + $47

                                        = $82

Given that the store charges 8% sales tax on all purchases.

Thus,

Tax amount  = 8% × 82

                      = 8/100 × 82

                      = 0.08 × 82

                      = 6.56

The total cost including the tax = Tax amount + The total purchase cost

                                                    = 6.56 + 82

                                                    = $88.56

Therefore, Michelle needs to pay $88.56 to pay for her purchase, including tax.
