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`

1 answer

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:

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:

cost_for_3_pounds = f(3)  # This will return 3.75
