weeeeeb [17]

Answer:

Step-by-step explanation:

First calculate the amount of notebooks and textbook

Cost of 2 notebooks = 2 *8.75

                                  = $ 17.5

Cost of 1 textbook = $ 74.95

Total cost = 17.5 + 74.95

                 = $ 92.45

Tax = 7% of total cost

      = 0.07 * 92.45

      = $ 6.47

Total cost = 92.45 +6.47

                 = $ 98.92
