The question is not complete, here is the complete question
"<em>DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"</em>
<h2 /><h2>Solution</h2><h2>Take note of the words "of" and "off" </h2>
1/4 of $48= 0.25*48=$12
so he thought he should pay $12
1/4 off $48= $48-$12= $36
now the difference is
36-12= $24
Answer: has a maximum
the maximum is 11
Step-by-step explanation:
f(x)= -5x^2-10x+6
the function f(x)= ax^2+bx+c=0 has a<0 so the equation has a maximum
I know V has the coordonate x=-b/2a, and y=-(b^2-4ac)/4a
b^2-4*a*c= (-10)^2-4*(-5)*6=100+120=220
so -b/2a=-(-10)/-2*5=+10/-10=-1 and
-(b^2-4ac)/4a=-220/4*(-5)=-220/-20=22/2=11
so V( -1, 11)
and the maximum is 11
A linear function is used to represent functions that have a constant rate

Linear functions</h3>
A linear function is represented as:
Where
- m represents the rate
- b represents the y-intercept
<h3>The equations </h3>
For restaurant warehouse:
Start by calculating the slope (m) using:
So, we have:
The equation is then calculated as:
So, we have:
Expand
For supply side:

All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.
