Answer:
Brand A is better buy as it cheaper than Brand B.
Explanation:
Given,
For Brand A:
Number of forks = 72
Cost = $3.89
For Brand B:
Number of forks = 96
Cost = $6.62
We have to find the unit rate for each brand.
For Brand A:
72 forks = $3.89
1 fork = Unit rate for Brand A
By Using Unitary method we get;
Unit rate for Brand A =

Again For Brand B:
96 forks = $6.62
1 fork = Unit rate for Brand B
By Using Unitary method we get;
Unit rate for Brand B =

From Above we can say that;
Unit rate of Brand A is less than Unit rate of Brand B.
Hence Brand A is better buy as it cheaper than Brand B.
