First subtract the amount she spent from the amount she had:
250,000-10,000=240,000

So she invested $240,000

Start with the given formula
Plug in p=240000, r=0.015, n=12, and t=10
Divide 0.015 by 12 to get 0.00125
Multiply the exponents 12 and 10 to get 120
Add 1 and 0.00125 to get 1.00125
Raise 1.00125 to the 120 th power to get 1.16172541654837
Multiply 240000 and 1.16172541654837 to get 278814.09997161

So after ten years, she will have $278,814.10 in her account.
