N-400 Filling fees

[BallerinaMenina]

I'm submitting my N-400 on Friday. The filing fee is $595 plus an $85 biometrics fee. Do those need to be two separate checks/money orders or do I add them together on one check or money order?
The instructions do not specify but they keep referring to payment in the plural.

Same cheque is fine.
