tolong dijawab dengan cara

2 1/4 = 9/4 = 2,25 kg
= 2 × 18.000 = 36.000
0,25 = 1/4 kg
1/4 × 18.000 = 4.500
harga telur = 36.000 - 4.500
= 40.500

3,5 kg
3 kg = 3 × 8.500 = 25.500
0,5 kg = 1/2 kg
1/2 × 8.500 = 4.250
harga tepung terigu
= 25.500 + 4.250
= 29.750

harga barang
40.500 + 29.750
= 70.250
