Explanation:

Step1: Recall unit - rate formula

The unit - rate (cost per banana) is calculated by dividing the total cost by the number of bananas. The formula is $\text{Unit Rate}=\frac{\text{Total Cost}}{\text{Number of Bananas}}$.

Step2: Identify values

We know that the total cost of bananas is $10$ dollars and the number of bananas is $15$.

Step3: Calculate unit rate

Substitute the values into the formula: $\text{Unit Rate}=\frac{10}{15}=\frac{2}{3}\approx0.67$ dollars per banana.

Answer:

$\frac{2}{3}$ dollars per banana (or approximately $0.67$ dollars per banana)
