Given data
Initial cost =$28
Final cost =$36
Required
The percentage change in cost
Percent change =final - initial/initial*100
Substitute
Percent change =36-28/28*100
Percent change =8/28*100
Percent change =0. 2857*100
Percent change =28.57%
1 x 19 = 19
2 x 9.5 = 19

Answer:
False ,false,true, true and true
Step-by-step explanation:
Use first differences. You are subtracting. Difference = Subtracting.
9 - x = 4
4 - x = -1
-1 - x = -6
Find for x.
9 - x = 4
- x = 5
x = -5
Therefore the answer is B.
Proof:
9 - 5 = 4
4 - 5 = -1
-1 - 5 = -6
