We need to find out how much 17 percent of 2,500 is, and then subtract that amount by 2,500. We can use proportions to use this. We can set up a fraction with x/2500 and another fraction with 17/100. Then, we need to cross multiply. This gives us 42,500. Next, we can divide by 100. This gives us 425. We know that they will save $425 if they decrease their energy use by 17%. We now need to subtract $425 from $2,500. This gives us $2,075. If the company is successful in decreasing their energy use by 17%, their bill would be $2,075.
Let's figure this out! Okay, so the original price is 24. 45% is taken off. Well, we just multiply 24 and 0.45! (45% = 45/100 = 0.45) When we do that, we get 10.8. Now, a common mistake is to just say 10.8 is the answer. Unfortunately for Charlie, that is only how much is being taken off. If 10.8 is being taken off 24, we subtract. 24 - 10.8 = 13.2. And there we have it!
Charlie payed $13.2.

Answer:x+2y=6
Step-by-step explanation: Given points: (4,1) and (-4,5)
To find equation we need a slope and a point through which the line passes.
slope = (y1-y2)/(x1-x2)
= 1-5/4-(-4)
= -4/8
= -1/2
let the first point be the passing point,
eq. of a line: (y-y1)=slope(x-x1)
=(y-1)=-1/2(x-4)
=2y-2=-x+4
=x+2y=6
