Hello, help please,
<<A group of donors and international agencies, including the Gates Foundation and the World Bank, is now promoting a plan (which is yet to be funded) for subsidising ACTs. The Affordable Medicines Facility-malaria (AMFm), as the scheme is called, aims to subsidise the purchase of ACTs to the tune of $1.4 billion-1.9 billion over five years. >>
What dose "to the
tune of $1.4 billion-1.9 billion
over five years" mean?
Would you please explain?
Many thanks in advance.
