Please check my answers.
If i got any wrong please tell me the right ones.
Please help me.
1 and 5 are correct. 2, 3, and 4 are wrong.
What are 2, 3, and 4?
remember: % change is calculated using the original amount
#1 b OK
#2 d because
the change is 54
54/450 = 12%
#3 a because
the change is 4
4/20 = 1/5 = 20%
#4 d because
the change is 12
12/150 = 8%
odd how you got some right and some wrong. They are all done the same way.
Go back and study your text materials and try again. You won't learn how to do these problems if I give you the answers.
