Answer

Explanation:

Step1: Calculate unit - rate of 6 - inch sandwich

The cost of a 6 - inch sandwich is $3.00. The unit rate (cost per inch) is calculated by dividing the total cost by the length. So, the unit rate $r_1=\frac{3.00}{6}= 0.50$ dollars per inch.

Step2: Calculate unit - rate of 12 - inch sandwich

The cost of a 12 - inch sandwich is $4.80. The unit rate (cost per inch) is calculated by dividing the total cost by the length. So, the unit rate $r_2=\frac{4.80}{12}=0.40$ dollars per inch.

Step3: Compare unit rates

Since $0.40<0.50$, the 12 - inch sandwich has a lower unit rate and is the better deal.

Answer:

A. A 12 - inch sandwich is the better deal because it costs $0.40 per inch, and the 6 - inch sandwich costs $0.50 per inch.
