Costs/revenues or cost/revenue?

I will minimise the cost and maximise the revenue.

It depends on whether you're talking about one cost and one revenue or several costs and several revenues.

Hi,

which one do people usually say?

I will minimize the cost and maximize the revenue.
I will minimize the costs and maximize the revenues.

Thanks

Didn't I answer that above?

See CSyder's response.

In my opinion, both are correct.

However, I am not sure which one will people usually say.

Based on the above answers, more people will say

I will minimize the cost and maximize the revenue.

This isn't a fixed phrase. Are you talking about one cost and one revenue, or multiple costs and multiple revenues? Use the singular or the plural according to the actual number of costs and revenues.
