Kua tāruatia ki te papatopenga
1.25n+15750=C
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
1.25n=C-15750
Tangohia te 15750 mai i ngā taha e rua.
\frac{1.25n}{1.25}=\frac{C-15750}{1.25}
Whakawehea ngā taha e rua o te whārite ki te 1.25, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
n=\frac{C-15750}{1.25}
Mā te whakawehe ki te 1.25 ka wetekia te whakareanga ki te 1.25.
n=\frac{4C}{5}-12600
Whakawehe C-15750 ki te 1.25 mā te whakarea C-15750 ki te tau huripoki o 1.25.
