Explanation:

Step1: Identify the given values

We know that 8 pieces of sushi cost $12. We need to find the cost of 1 piece.

Step2: Apply the unit rate formula

The unit rate (cost per piece) is calculated by dividing the total cost by the number of pieces. So we use the formula: $\text{Unit Rate} = \frac{\text{Total Cost}}{\text{Number of Pieces}}$.
Substituting the given values: $\text{Unit Rate} = \frac{12}{8}$.

Step3: Simplify the fraction

Simplify $\frac{12}{8}$ by dividing both the numerator and the denominator by their greatest common divisor, which is 4.
$\frac{12\div4}{8\div4} = \frac{3}{2} = 1.5$.

Answer:

The cost of 1 piece of sushi from Dragon Sushi is $1.5.
