You never switch a neutral wire, only hots. hooking both hot and neutral to the same switch will result in a short when the swith is turned on.
Divide 20A by the Amps listed on the label of each fixture ballast. A T8 bulb will use an electronic ballast. They generally run 1A for four 4 foot bulbs. Try 15 four bulb fixtures per circuit and use a 20A rated switch.

The 20A breaker can handle (25%) more power than the 15A breaker, because of this the wires used inside the walls is larger. Some circuits must be 20A, the laundry and kitchen are examples of 20A circuits.
The National Electrical Code (US) allows up to thirteen 20 amp receptacles on a 20 amp circuit. 120V x 20A = 2400 VA each duplex receptacle is calculated at 180 VA 2400 / 180 = 13.3333 receptacles, since you can't put a third of a receptacle in, you have to round down to 13.

20a + 45 = 5(4a + 9)
-4(5a-3) = -20a + 12
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
