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.
