  1. 1, 3, 11, 20

  3. 10, 30, 100, 100    
  4. 20, 40, 100, 200    

Hint:

In this question, cost of renting a bicycle for an hour is given with a maximum daily fee of $100. We are required to find the cost for renting bicycle for 1, 3, 11, and 20 hours.

The correct answer is: 10, 30, 100, 100


    Step by step solution:
    the cost of renting bicycles an hour = $10
    The maximum daily fee for renting bicycle is $100.
    Therefore,
    cost of renting bicycle for 1 hour = $10 x 1 = $10
    cost of renting bicycle for 3 hours = $10 x 3 = $30
    cost of renting bicycle for 11 hours = $10 x 11 = $110, but since maximum daily fee for renting bicycle is $100 the cost of renting for 11 hours is $100.
    cost of renting bicycle for 20 hours  = $10 x 20 = $200, but since maximum daily fee for renting bicycle is $100 the cost of renting for 20 hours is $100.
    So, the cost for renting bicycle for 1, 3, 11, and 20 hours is $10, 30, 100, and 100.
    Hence, option(a) is the correct option.
