The attendance of a soccer tournament was 160 people. this was 125% of last year's attendance. how many people attended the tournament last year?show me all the work i'm doing work with a friend and we are arguing over this problem

20

Step-by-step explanation: you get 20 when you do a proportion: 125% over 1,000 then x over 160. You have to cross multiply, 125 times 160 and get 20,000 after that you multiply 1,000 times x and get 1,000x. After doing those simple steps you divide 1,000 by 20,000 and 20.
