If it is 4 for $5 we would create a ratio and unit rate to test out all of the options
We want to know how much one costs first 4/5 = 1/$1.25
So you test out all options:
A. 1.25/1=6.25/5 this is correct B. 1.25/1=3.75/3 this is correct C. 1.25/1=9/6 this is NOT correct D. 1.25/1=1.5/1 this is NOT correct E. 1.25/1=12.5/10 this is correct
