Answer 1

Answer:

19.05-0.44=18.61

18.61-0.84=17.77

17.77-1.19=16.58

Answer 2

Answer:

10.58

Step-by-step explanation:

Asume her electric bill was $A in june.

in July: A+18.02

in Augest: (A+18.02)+1.03

in September: ((A+18.02)+1.03)-0.44

and so on...

After 5 months it should be:

((((A+18.02)+1.03)-0.44)-6.84)-1.19 = A + 10.58

So after 5 months the total change is 10.58
