Solution

To find the unit price for each bag, we need to divide the total cost of each bag by its weight.

For the 7.26-kg bag: 14.98÷7.26kg=14.98 ÷ 7.26 kg = 2.06 per kg

For the 7.94-kg bag: 17.54÷7.94kg=17.54 ÷ 7.94 kg = 2.21 per kg

Therefore, the 7.26-kg bag is the better buy because it has a lower unit price.
