Troy saved 2/3 of his paycheck and spent 1/3 of the remaining money. He was then left with $12. What was the original value of Troy's paycheck?

3 answers

2/3 * 2/3 * p = 12
4/9 * p = 12
p = 9 * 3 = 27
2/3 * 1/3 = 2/9
so
2/9 x = 12
solve for x
I assumed that "remaining money" is what he saved.
Oobleck assumed that "remaining money" was what he did not save.
Who knows ?
