Yes, In fact I do know the answer to this:

First: I have an estimate on the recertification cost from a credible
industry source.

Second: I have a budgetary price for the ELT

Third: I learned division in school.

Given the imprecsions on the estimates, specifying the result as
"several ELT's" is a sensible treatment of one significant digit.

If they thought there were a credible indication that any such
dependencies existed, they probably would.

The fact that you didn't include a strawman for such an indication,
seen in the historical context that railroads practically invented
1-hour wide timezones, counter-indicates such dependencies.
