Nomor 1 :
Kartu Tono:
1 kartu hijau + 2 kartu merah
= 17 + ( -14 + ( -14))
= 17 + ( -28 )
= -11
Kartu Bayu:
1 Kartu hijau + 1 kartu kuning + kartu merah
= 17 + ( -8 ) + ( -14 )
= 9 + ( -14 )
= -5
Selisih kartu = -11 - ( -5 ) = -6
Nomor 2 :
Awal = -10°c
Dimasak naik = 98°c
Dihidangkan turun = 29°c
Suhu daging saat dihidangkan:
-10 + 98 - 29
= 88 - 29
= 59°C
