Ike's bikes has mountain bikes that usually sell for $275 on sale for $220. mike used this ratio to find the percent change. is he correct? explain.

No. Mike wrote the ratio as the amount of change to the new amount. He should have used the ratio of the amount of change to the original amount, which is 55

55/275

, or 20%.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
