Estelle is having her birthday party at Gold Frames Art Museum this year. A party package costs $265 and covers the entrance fee for guests, a private party room, and an activity guide. Estelle upgraded her package to include a favor for each of her 8 guests, bringing the total to $305.

Which equation can you use to find f, the cost of each favor?
How much did each favor cost?

The equation that can be used to find the cost of each favor is:

305 - 265 = 8f

To solve for f, we need to subtract the base cost of the party package from the upgraded total cost. Then, divide the result by the number of guests (8).

305 - 265 = 40
40 ÷ 8 = 5

Each favor costs $5.
