Kua tāruatia ki te papatopenga
8748=P\left(1-\frac{9}{50}\right)^{3}
Whakahekea te hautanga \frac{18}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
8748=P\times \left(\frac{41}{50}\right)^{3}
Tangohia te \frac{9}{50} i te 1, ka \frac{41}{50}.
8748=P\times \frac{68921}{125000}
Tātaihia te \frac{41}{50} mā te pū o 3, kia riro ko \frac{68921}{125000}.
P\times \frac{68921}{125000}=8748
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
P=8748\times \frac{125000}{68921}
Me whakarea ngā taha e rua ki te \frac{125000}{68921}, te tau utu o \frac{68921}{125000}.
P=\frac{1093500000}{68921}
Whakareatia te 8748 ki te \frac{125000}{68921}, ka \frac{1093500000}{68921}.
