Explanation:
If mum was 23 seven years ago, that means she is currently 23 + 7 = 30 years old.
In seven years, she will be 30 + 7 = 37 years old.
Answer:
the answer would be 30 because you would be adding 7 years by 23 and since you said years ago i think you meant by years old
you're welcome if this help :)
