lol....then ur answer should be...
299.999999 repeating. and it is approximate to 300

u can elimite the decimal by adding 250 and 20. so the total spending will be 270. 270 + the change of 30 then it will be 300 exactly~~~lol
250/3 = 83.3 repeating
83.3 repeating + 10 = 93.3 repeating

93.3 repeating*3 = 280

and 280+20=300

so.. i dont' know what you are talking about :spin:
