Your equation would be 2,500x + 363,270=1.5 million. then you subtract 363,270 from 1.5 million and get 1,136,730. afterwards you get 2,500x=1,136,730. divide 1,136,730/2,500 and your answer will be 454 wins to accumulate 1.5 million dollars
1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand cross multiply because this is a proportion (1)(x) = (7.15)(1000) x = 7150 <=== Sophia got 7150 rand
