Hey mate. Here is your Answer:
f(x) = 50 + 25(x - 1)
Step-by-step explanation:
Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:
Lifetime membership fee = $ 50
First video game is free
Then any video game purchased after = $ 25.
Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:
f(x) = 50 + 25(x - 1)
If x = 1, then f(1) = 50 + 0 = 50
If x = 2, then f(2) = 50 + 25 = 75
If x = 5, then f(5) = 50 + 100 = 150
