Implementing Portuguese orthographic accord to cost Mozambique around $100 million

An article here in Portuguese says that the cost to implement the Portuguese orthographic accord in Mozambique will end up costing around $100 million - the article says at one point that it will be "at least $100 million" and then estimates the cost at $72.3 million, so we'll just go with $100 as a rough estimate. The cost would come from new textbooks, training teachers, journalists, public employees, etc.
