A computer company gives a discount of 10% on a new piece of software. If it makes a profit of 9%, what percent does the marked price exceed the cost price?

OpenStudy (anonymous):

8.1%

OpenStudy (anonymous):

how did you come up with that answer

OpenStudy (anonymous):

you figure that 10% off a price makes it a 90% of the original price

then if they make 9% profit off of that 90% of the original price, you have .09*90 and you get 8.1 which is the percent of the original price.
