First time posting, so I'm sorry if this is in the wrong place.
I'm looking at math destroyer practice test 2, problem 8:
Donna says that she was 21 when her daughter Trish was born. When asked how old her daughter is today, Donna said that in 6 years she will be 6 more than twice her daughter's age. How old is Trish?
Seems extremely simple. When I do the math, I get 21. Why on Earth are they saying the answer is 9? That doesn't even make sense. If her daughter is 9, then in 6 years, Donna will be 24 (6 more than 9*2). Which means Donna is currently 18 and her daughter isn't even born yet? Am I just missing something obvious?? Really scares me that I am using this resource to study, unless I'm embarrassingly wrong of course.
