Java invests in a new mutual fund. The fund averages 10% growth annually for the first three years, but it loses 30% of its value in the fourth year. At the end of four years, the value of the mutual fund is approximately what percent of the amount Java originally paid?
A. 93%
B. 90%
C. 88%
D. 85%
E. 80%
The OA is A.
I can take an amount for initial investment, for example 100, then of the first three years I get 100*1.10^3 = 133 approximately.
Then in the fourth year loses 30%, then 133*0.7 = 93 option A.
Experts, it is correct my solution? I'm not completely sure. Thanks.

So after 4 years it's worth:
