Question

Help me!!!!!!!!! Also, can you tell me how to find the percentage change, i forgot lol

Answer 1

Answer:

#1 = 10.71% decrease (not sure if you should write -10.71%)

#2 = 49.29% decrease (-49.29%) (-49.30% rounded)

#3 = 5.4% increase

#4 = 34.26% decrease (-34.26%. -34.27 if your teacher wants it rounded.)

Step-by-step explanation:

Original:28

New:25

Increase ÷ Original Number × 100.

28-25 =3

3/28 = 0.1071

0,1071*100= 10.71

Original:21.2

New:10.75

21.2-10.75= 10.45

10.45/21.2 = 0.4929

0.4929*100 = 49.29 (49.30)

Original:37

New:39

difference = 2

2/37 = 0.054

0.054*100 = 5.4

Original: $4.29

New:$2.82

4.29-2.82 = 1.47

1.47/4.29 = 0.3426

0.3426*100 = 34.26 (34.27)

Hope this helps! Have a great day! Also, let me know if it is correct.
