The hypothetical exercise assumes that the family is still intact. You add the two incomes together to obtain the hypothetical family income and then you use other estimates from Statistics Canada, for example, which say, " If a family had this sort of income, how much would be spent on the child?" You then take those two incomes in proportion and say, " One parent has 60 per cent of the income while the other has 40 per cent.
On commence en posant l'hypothèse que la famille est toujours intacte; on additionne donc les deux revenus pour avoir le revenu familial hypothétique, puis on utilise des estimations, par exemple celles de Statistique Canada, qui permettent de déterminer, pour un tel revenu familial, la somme qui est consacrée à l'enfant.
