A machine can lift a weight of 20 kg on the first day. The weight it can lift increases by 20 percent each day. How much total weight can the machine lift on the 4th day?(1 point) Responses 74.42 kg 74.42 kg 107.36 kg 107.36 kg 34.56 kg 34.56 kg 80 kg
To solve this problem, we need to calculate the weight the machine can lift on the 4th day.
On the first day, the machine can lift 20 kg.
On the second day, the weight it can lift is 20 kg * 1.20 = 24 kg.
On the third day, the weight it can lift is 24 kg * 1.20 = 28.80 kg.
On the fourth day, the weight it can lift is 28.80 kg * 1.20 = 34.56 kg.
Therefore, the total weight the machine can lift on the 4th day is 34.56 kg.
So, the correct answer is: 34.56 kg
