In a store a sweater costs $27.99 plus 6% sales tax. the same sweater in a catalog is $20.99 plus 6% sales tax and $4.00 for shipping and handling. how much more or less is the sweater in the store verses the catalog? a. $7.42 more in the store c. $3.42 less in the store b. $3.42 more in the store d. $7.42 less in the store

Option b. $3.42 more in store.

Step-by-step explanation:

The cost of a sweater in a store = $27.99 + 6% (sales tax)

The cost of a sweater in a store = 27.99 + (6% of 27.99)

                                                     = 27.99 + (0.06 × 27.99)

                                                     = 27.99 + 1.6794

                                                     = $29.6694 ≈ $29.67

Price of the same sweater in a catalog = $20.99 + 6% (sales tax) + $4.00 (shipping)

                                                    = 20.99 + (6% × 20.99) + 4.00

                                                    = 24.99 + (0.06 × 20.99)

                                                    = 24.99 + 1.2594

                                                    = 26.2494 ≈ $26.25

Difference between the price = 29.67 - 26.25 = $3.42 more in store.

Option b. $3.42 more in store.
