We are given that a house increases its value by 17%. To determine the value it increased we need to multiply by 17/100, like this:
[tex]335000\times\frac{17}{100}=56950[/tex]To determine the current value we add the amount it increased to the original price:
[tex]335000+56950=391950[/tex]Therefore, we have
Increase value: $56950
current value: $391950
