Answer: The cost of each favor is $5.
Step-by-step explanation: To find the cost of each favor (f), we can set up an equation based on the given information.
We know that the original party package costs $265, and Estelle upgraded the package to include favors for each of her 8 guests, bringing the total cost to $305.
Let's break down the equation:
Original package cost + Cost of favors = Total cost
$265 + 8f = $305
In this equation, f represents the cost of each favor.
To find the value of f, we need to solve the equation.
First, let's isolate the term with f:
8f = $305 - $265
8f = $40
Now, divide both sides of the equation by 8:
f = $40 / 8
f = $5
Therefore, the cost of each favor is $5.
So, the equation we can use to find f, the cost of each favor, is 8f = $40.
