33

Explanation:

If Hayley is x years old then her dad is (x+25) years. In 17 years she will be (x+17) and he will be (x+25+17)=(x+42)
But if he is twice her age then (x+42)=2(x+17)
#=># x+42=2x+34
#=># 42=x+34 after subtracting #x# from both sides
#=># 8=x after subtracting 34from both sides

So if she is 8 years, her dad is 8+25=33
