Answer 1

To find the unit price, divide the cost of the bag into the kilograms of each bag:

1. $12.24 into 6.35kg:

$\frac{12.24}{6.35}\approx1.93$

2. $13.99 into 7.48kg:

$\frac{13.99}{7.48}\approx1.87$Then, Unit price for the 6.35 kg bag: $1.93 per kgUnit price for the 7.48kg bag: $1.87 per kgThe better buy: The 7.48-kg bag
