Answer:
So she must achieve about 11.61 %
Explanation:
Amount invest by Kathy = $50000
She wanted to buy a home for $150000
Time of investment = 10 years
We have to find the return which she received
Let she receives x return
So according to question [tex]50000\times (1+x)^{10}=150000[/tex]
[tex](1+x)^{10}=3[/tex]
[tex](1+x)=3^{0.1}[/tex]
[tex](1+x)=1.1161[/tex]
[tex]x=0.1161=11.61%[/tex]
So she must achieve about 11.61 %
