Question

Apples at the local farmer's market cost $1.25 per pound.



Write a function rule`f` that gives the total cost of apples in terms of the number of pounds, `x`

Answer 1

To write a function that gives the total cost of apples in terms of the number of pounds, we can use the following linear equation:

\[
\text{Total Cost} = \text{Price per Pound} \times \text{Number of Pounds}
\]

Given that the price per pound of apples is $1.25, we can define the function \( f(x) \) as follows:

```python
def f(x):
price_per_pound = 1.25
total_cost = price_per_pound * x
return total_cost
```

In this function:
- `x` is the number of pounds of apples.
- `price_per_pound` is set to 1.25.
- The function calculates the total cost by multiplying the price per pound by the number of pounds `x`.
- It returns the total cost.

You can call this function with a specific number of pounds to get the total cost, for example:

```python
cost_for_3_pounds = f(3) # This will return 3.75
```
