Steps to Solve
- Calculate Bananas per Dollar
To find the cost in terms of bananas per dollar, we need to divide the total number of bananas by the total cost in dollars.
We have:
- Total bananas = 10
- Total cost = 5 dollars
So, the calculation is: $$ \text{Bananas per dollar} = \frac{\text{Total bananas}}{\text{Total cost}} = \frac{10 \text{ bananas}}{5 \text{ dollars}} $$
- Simplify the Calculation
Now simplify the equation: $$ \text{Bananas per dollar} = \frac{10}{5} = 2 $$
This means Ariana gets 2 bananas for every dollar spent.
- Summary of the Result
This result shows us the unit rate, which is the number of bananas that can be bought per dollar. Thus, we conclude:
- Cost in terms of bananas per dollar is 2.
The cost of the bananas is $2$ bananas per dollar.
