Part 1.

(I) Year 2018:

Cost of notebooks = 8 x 2 = 16

Cost of calculator = 1 x 104 = 104

Cost of large coffee = 150 x 2 = 300

Cost of energy drinks = 40 x 4 = 160

Cost of textbooks = 10 x 85 = 850

Total cost = 16 + 104 + 300 + 160 + 850 = 1,430

(II) Year 2019:

Cost of notebooks = 8 x 4 = 32

Cost of calculator = 1 x 134 = 134

Cost of large coffee = 150 x 2 = 300

Cost of energy drinks = 40 x 5 = 200

Cost of textbooks = 10 x 105 = 1,050

Total cost = 32 + 134 + 300 + 200 + 1,050 = 1,716
