Hello,
I'd like to say that corn prices did not double, but increased *5. - And I've no idea how to do that: did they increase five times, for five times??
Could you help me, please?
Thanks a lot.

You could say
'Corn prices increased by a factor of five'
'The price of corn quintupled'
Prices increased five-fold.
You could also say 'corn prices became five times as much'
