listening experience. The function f(x)=20x+x+ 50+ 30(x+2) represents his total

each person needs a $1 license for the website (1x), it costs $50 to get a domain name, a
nd it costs $30 for each x + 2 iPod Nanos (he's keeping 2 for himself).
a. Find the value of f(5). (Hint: plug in 5 for x and simplify!)
b. Determine how many customers he has if his total cost is $416?
