Question

Each time Gertrude gets paid, 10% of her pay check goes to taxes. Last week, $40 was taken out of her check for taxes. What was the amount of Gertrude's pay check last week, in dollars?

Answer 1

Alright you take 40 dollars, and multiply it by 10%, which is .10 in decimal form. Then you get 4 dollars. You then subtract 4 dollars out of 40 to get 36$
So Gertrude brought home 36$, and 4$ went to taxes :)
