Answer:
9.375% rounded 9%
Explanation:
so if the original price is 1200 that is equal to 100% so if 1200=100% then to get ten percent of 1200 u would divide 1200 by 10 which gets you 120 and if the sale price is 1125 then u do 1125 divide by 120 because that is 10% so that gives you 9.357 and you add you percentage on and there is your anwser hope this helped ;)
