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

Respuesta :

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
