Answer:The unit price for the bags are 2.505 and 2.429.
Step-by-step explanation:
Scott paid 19.99 for a 7.98kg bag of dog food. The unit price will be to divide 19.99 by 7.98.
Unit price= 19.99/7.98
= 2.505
Few weeks later, Scott paid 20.38 for an 8.39kg bag at a different store. The unit price will be to divide 20.38 by 8.39
Unit price= 20.38/8.39
= 2.429
