Answer:
Store 2
Step-by-step explanation:
Given
1. $4.50 for 5 pounds
2. $1/5 for 1/3 pounds
3. $4.00 for 5 pounds
Required
Determine the store with the lowest unit rate
To do this, we simply divide the price by the weights in each store
For Store 1:
[tex]Unit\ Rate = \frac{\$4.50}{5\ lb}[/tex]
[tex]Unit\ Rate = \$0.9/lb[/tex]
For Store 2:
[tex]Unit\ Rate = \frac{\$1/5}{1/3\ lb}[/tex]
[tex]Unit\ Rate = \$0.6/lb[/tex]
For Store 3:
[tex]Unit\ Rate = \frac{\$4.00}{5\ lb}[/tex]
[tex]Unit\ Rate = \$0.8/lb[/tex]
Comparing the unit rates of the three stores, we can conclude that store 2 offers the least unit rate
