Question

Alfred needs to buy small pumpkins that cost $2.75 each. The function he uses is ()=2.75. Use the function to determine the cost of 25 pumpkins.

Answer 1

The calculated cost of 25 pumpkins is $68.75 using f(x) = 2.75x

How to determine the cost of 25 pumpkins.

From the question, we have the following parameters that can be used in our computation:

f(x) = 2.75x

Also, we have

Pumpkins = 25

Substitute the known values into the equation

f(25) = 2.75 * 25

Evaluate

f(25) = 68.75

Hence. the cost of 25 pumpkins is $68.75

Answer 2

From the question, we have a linear function for the cost of each pumpkin, and this function is:

`f(x)=2.75x`

As we can see, the cost for one pumpkin is:

`f(1)=2.75(1)=\text{ \$2.75}`

Now, to find the cost for 25 pumpkins, we need to substitute the value of x = 25 into the function, since this is a function that gives us the cost as a function of the number of pumpkins:

`\begin{gathered} f(x)=2.75x \\ \\ f(25)=2.75(25)=68.75 \\ \\ f(25)=68.75 \\ \\ \end{gathered}`

As we can see, we multiply 2.75 times 25, and we got 68.75.

Therefore, in summary, it will cost $68.75 for 25 pumpkins.
