The total cost of buying blank CDs from the internet (T_I) is 26.00 + 27.99 + 31.50 + 32.75 + 27.00 + 27.98 + 24.75 + 28.15 + 29.99 + 29.99 = 286.10. The total cost of buying blank CDs from local electronic stores (T_E) is 33.98 + 37.75 + 38.99 + 35.79 + 33.99 + 34.79 + 29.98 + 33.00 + 32.00 + 29.99 = 339.26. Therefore, T_I + T_E = 286.10 + 339.26 = 625.36.
