Difficulty with a Type Z example
Duncan is twice as old as Sebastian will be next year. Isabella is 8. Sebastian is three years older than Isabella was last year.
How many years old is Duncan?
Good Son put 22. I think it is 22, but IPS answer book says 14.
D = 2((8-1+3)+1)
D = 2 * 11
Please put me out of my misery and tell me the book is wrong or I am mathematically challenged!
