Tom is planning a birthday party for his nephew at the local skating rink. There is a standard fee of $25 plus an additional $3 for each child. Which function would best indicate the cost for the party
For this case, the first thing we must do is define variables: x: number of children y: total cost We now write the equation that models the problem. We have then: y = 3x + 25 Answer: A function that would best indicate the cost for the party is: y = 3x + 25
