1 kg =1000g

1 ton = 1000 kg

Convert it into international unit kg first.

Because 1 ton = 1000kg, a ton is 2950 yuan, so the price of 1kg soybean meal is

2950÷ 1000=2.95 (yuan/kg)

Since 1 kg =500g, 140 kg is converted into kg.

140kg =140× 500÷1000 = 70kg.

It is found from the above formula that 1kg is 2.95 yuan, and 140 kg is 70kg, so the price of 1 package is

2.95×70=206.5 yuan
