I really need help with this question.... Darian's IRA has fallen 12.6% since the beginning of the year to 142,500.49. What was the value of her IRA at the beginning of the year?

143500.49 x .126 =18081.06 18081.06+143500.49=$161581.55 is your answer

Assume your initial amount(I) is 100% if you decrease by 12.6% 100-12.6 = 87.4% Then 142,500.49 = 0.874*I Just divide by .874 to find I
