Answer:
He spent around $ 52.17 in each month.
Step-by-step explanation:
Last year the power bill price = $ 626.14 ≈ $ 626
We know that in a year 12 months. so power bill of each month in last year is calculated as follows
![Power \ bill \ of \ each \ month = \frac{Total \ bill \ of \ the \ year}{12}](https://tex.z-dn.net/?f=Power%20%5C%20bill%20%5C%20of%20%5C%20each%20%5C%20month%20%3D%20%5Cfrac%7BTotal%20%5C%20bill%20%5C%20of%20%20%5C%20the%20%5C%20year%7D%7B12%7D)
![Power \ bill \ of \ each \ month = \frac{626}{12}](https://tex.z-dn.net/?f=Power%20%5C%20bill%20%5C%20of%20%5C%20each%20%5C%20month%20%3D%20%5Cfrac%7B626%7D%7B12%7D)
$ 52.17
Therefore he spent around $ 52.17 in each month.
I think the answer is C.I’m not sure let me know what you get .
The answer will be 43. i hope this helps you out! :)
The key thing here is that x is the number of years AFTER 1990, therefore for part A plug in 0 to get 743
For part B plug in 12 and 17 then subtract the smaller from larger.
I got 1470.6 for 2007 and 1380.2 for 2002
Subtracting gives 90.4, which rounds to 90 because .4 of a prisoner doesn't make sense
Final answer:
(A) 743
(B) 90
Hope I helped :)
(new - original)/original = mark up
(78.08-64)/64= mark up
14.08/64 =mark up
.22 = mark up
multiply by 100 to get to a percent
mark up = 22 percent
