  1.  Suppose you want the total price for 2 adults and 1 child of 2 years
      of age.

      Children aged 0-3 are never included in the rate's occupancy,
      so here you should take the double occupancy rate and divide by 2 to
      get the unit price. Then, multiply by the percentage rate and sum
      with the rate to get the total price.

      `unit price ` = 110 / 2 = 55

      `total price` = 110 + 55 * 0.1 = 115.5

  1.  Suppose you want the total price for 1 adult and 2 children, both of 5
      years of age.

      Children aged 4-10 are preferably included in the rate's
      occupancy. you should start by looking for a 3 adult rate since both
      children are preferably included in the rate's occupancy. Since
      that doesn't exist you should fall back to the 2 adult rate and then,
      take this rate and divide by two to get the unit price. Finally,
      multiply by the percentage rate and sum with the scaled rate to
      get the total price.

      `unit price` = 110 / 2 = 55

      `total price` = 55 + 55 * 0.3 + 55 * 0.3 = 88

  1.  Suppose you want the total price for 1 adult and 1 child of 17
      years of age.

      Children aged 11-17 are always included in the rate's occupancy, so,
      in this case, take the double occupancy rate and divide by 2 to get
      the unit price. Then, deduct it by the discount amount and sum with
      the scaled rate to get the total price.

      `unit price` = 110 / 2 = 55

      `total price` = 55 + (55 - 10) = 100
