DM1 3 // Lab 08 4 5 #include > item2; cin >> item3; cin >> item4; cin >> item5; 29 // Calculate the subtotal, taxes, and total. Subtotal = itemi + item2 + item + item4 + items; I // Output the item amounts, dashes, subtotal, taxes, and total as shown in the examples Tax = Subtotal * TAX RATE; Total = Subtotal + Tax; 30 31 32 33 34 35 36 37 38 39 40 41 42 cout
