REALLY EASY PLEASE HELP!

Answer:
The 100 g bag is the better value.
Step-by-step explanation:
Calculate the unit prices as follows:
1.49 British pounds
------------------------------ = 0.0124 British pounds / gram
120 grams
0.89 British pounds
------------------------------ = 0.0089 British pounds / gram
100 grams
The 100 g bag is the better value.
The cheaper one is better.
It's 0.89. 0.89 times 2 is 1.78, and 1.78 is greater than the other sweet's price, which is not even half doubled.
Hope my bad explaining help, eheh.
