The number of visitors to a park is expected to follow the function v(x) = 5(x − 1), where x is the number of days since opening. On the first day, there will be a ceremony with 20 people in attendance. What is the function that shows total visitors, including the ceremony?

c(x) = 20 + 5(x − 1)
c(x) = 20 − 5(x − 1)
c(x) = 5(x − 1) − 20
c(x) = 100x − 100

 c(x) = 20 + 5(x − 1)
 c(x) = 20 − 5(x − 1)
 c(x) = 5(x − 1) − 20
 c(x) = 100x − 100

Hint: Try this
c(x) = v(x) + 20
