To solve this problem, we must figure out how many kilograms of rice Alice bought. To do this, we should multiply how many total bags of rice Alice bought by the weight of each bag.
Alice bought 14 bags of white rice and 4 bags of brown rice. Because 14+4=18, Alice bought 18 bags of rice total.
Next, we should multiply Alice’s 18 bags of rice by the 7 kg weight per bag.
18*7=126
This means that the answer is A. 126 kilograms.
Hope this helps!
