Question 995529
algebraically you would solve this as follows:


x = original price.


x - .10 * x = 45


.90 * x = 45


x = 45 /.90


x = 50


your original price is 50.


if your original price is 50 and you sell it for 65, then the percent gain can be repsented algebraically as follows:


50 + x * 50 = 65


x * 50 = 65 - 50


x * 50 = 15


x = 15 / 50


x = .30 * 100 = 30%.


if you sell it for 45 at a loss of 10%, then the original price must have been 50.


if the original price is 50 and you sell it for 65, then your percent again would be 30%.
