He is charged $2.50 for every additional hour of renting the bike.Select all the functions that can be used to find the total amount that Richard is charged, f(n), for renting the bike for n hours.f(n) = 2.50n + 7f(n) = 4.50n + 2.50f(1) = 2.50; f(n) = f(n - 1) + 7, for n ≥ 2f(1) = 4.50; f(n) = f(n - 1) + 2.50, for n ≥ 2f(n) = 2.50n + 4.50f(1) = 7; f(n) = f(n - 1) + 2.50, for n ≥ 2
Accepted Solution
A:
Be: Number of hours: n
The cost of renting a bike for the first hour is $7: n=1→f(n)=f(1)=$7
He is charged $2.50 for every additional hour of renting the bike: f(n)=f(n-1)+2.50, for n ≥ 2
f(1)=7; f(n)=f(n-1)+2.50, for n ≥ 2 (sixth option)
