Hello all,
please help me out with the following

! I'm not sure which of the two sentences is correct (if any lol)
1.) "Both in the countries listed in the table and overall in Europe, the AMOUNT of money invested in education increased between 1990 and 1995."
2.) "Both in the countries listed in the table and overall in Europe, the AMOUNTS of money invested in education increased between 1990 and 1995."
Which would you prefer? Could you please indicate in your reply whether you are a native speaker of English? Thank you very much!
Bye,
Luzi
