Answer:
50 kg sacks of rice for $59.00.
Step-by-step explanation:
Lets do the math. First, I want to see how much 50 kg of of the first option costs.
$15.45 is worth 10kg.
$15.45*3=$46.35
Since the fourth on is free, the sum will stay the same.
$46.35+$15.45=$61.80.
50 kg of the first option is worth $61.80.
50 kg of the second option is worth $59.00.
$61.80 > $59.00.
So, the second option is cheaper and the better deal.
