1 answer:

7 0

1-39 ODD:
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39
Now you'd add them all up.
1+3+5+7+9 = 25
11+13+15+17+19 = 75
21+23+25+27+29 = 125
31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.

lyudmila [28]

The bill will be 18,480 if they are successful.

Step-by-step explanation:

Given,

Current bill of company = 22000

Energy usage to decrease = 16%

Amount of decreased usage = 16% of current bill

Amount of decreased usage = $\frac{16}{100}*22000$

Amount of decreased usage = $0.16*22000$

Amount of decreased usage = 3520

Bill after decreased usage = Current bill - Amount of decreased usage

Bill after decreased usage = 22000 - 3520 = 18480

The bill will be 18,480 if they are successful.
