Sarah investment in stock grew 12% to $392. How much did she invest?

Question

lgbasallote · Answer

i think the algebraic equation is let x = original stock
so..

x + .12x = 392
1.12x = 392
x = 350

so 0.12x (investment) = 42

anonymous · Answer

actually you were correct to look for x = so your answer of 350 is correct.  $42 reflects the amount of growth.
