"Οι επιχειρήσεις βοηθούν την οικονομία."

[ZoranMudronja]

the businesses ARE the economy (just saying)

No, the people are. Businesses would be nothing without consumers.

" Businesses help the economy" Was not accepted, it is a typo, one correct answer was "Businesses helpaid the economy". I imagine this was meant to be aid or help.
