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.

The function rule f that gives the total cost of apples in terms of the number of pounds, x, can be expressed as:

f(x) = 1.25x

The price of a pizza is $7.99 plus an additional $1.35 for each topping. Write a function rule f that gives the total price as a function of the number of toppings, x.

The function rule f that gives the total price as a function of the number of toppings, x, can be expressed as:

f(x) = 7.99 + 1.35x

To write a function rule that gives the total cost of apples in terms of the number of pounds, x, we'll first consider the given information.

We know that apples at the local farmer's market cost $1.25 per pound. That means for every pound of apples, it will cost $1.25.

So, we can write the function rule as follows:

f(x) = 1.25x

In this function, f(x) represents the total cost of apples and x represents the number of pounds of apples. By multiplying the number of pounds (x) by the cost per pound ($1.25), we can calculate the total cost.
