Both of them are wrong 525 rounds to 530! The way I was taught may be different then how you were taught!! 5 and up rounds up 4 and down rounds down! :) I hope this helped!
250% can be converted into a fraction 250/100 or into a decimal 2.50. so 250% of 28,000 is 2.50 times 28,000 which is 70,000. 28,000 is increased by 70,000 to 98,000
