Step-by-step explanation:
the total cost is, of course, first the cost to buy the copier, and then the running costs per copy made.
it is really that easy.
the equations just put this into mathematical form :
A
y = 0.02×x + 800
B
y = 0.06×x + 600
please notice, we put $600 or $800 in as constant term, because these costs are the starting costs that we have, even if we never make a single copy (x = 0).
and then the total cost goes up with every copy we make.
I cannot draw here.
so, to find the number of copies where both copier systems would cost the same, means we have to say both equating deliver the same result :
0.02×x + 800 = 0.06×x + 600
200 = 0.04×x
x = 200 / 0.04 = 5000
when making 5000 copies both costs are the same.
Expected value E(x) = 0.9994(150000 - 181) = 0.9994 x 149819 = $149,729.11
Answer:
x=106
Step-by-step explanation:
Let's solve your equation step-by-step.
−12+x−34=60
Step 1: Simplify both sides of the equation.
−12+x−34=60
−12+x+−34=60
(x)+(−12+−34)=60(Combine Like Terms)
x+−46=60
x−46=60
Step 2: Add 46 to both sides.
x−46+46=60+46
x=106
The answer is 25%.
First: work out the difference between the two numbers you are comparing.
Decrease = Original Number - New Number
35-28=7
Then: divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100
7÷
28=.25
.25*100=25
