I have a big math test tomorrow and a question on the review packet my teacher made for my class just doesn't make sense to me.

Here it is...
For a 'Black Friday' sale, everything in a store is 10% off the original price. If Ana purchased an item that was marked with a sale price of $40, what was the original price?

My teacher said the answer was $44.44 but I don't understand how she got that, can someone help please?

My hand writing is messy but you would take. 40$ × 0.10 . then you would take 40$ and subtract it from the answer you received from multiplying and then you have your answer.
