Answer:
The first offer: 100.80 for 4kg
Step-by-step explanation:
To find the best offer, we just need to find the price per kilogram, and we do this by dividing the price by the number of kg:
100.80 for 4kg: 100.8/4 = 25.2 per kg
170.50 for 5kg: 170.5/5 = 34.1 per kg
260.60 for 6kg: 260.6/6 = 43.43 per kg
320.40 for 7kg: 320.4/7 = 45.77 per kg
The first offer has the smaller price per kg, so it is the best offer.
