First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
Hello there!
Answer:
$24
Step-by-step explanation:
In order to find the answer to your problem, we're going to need to find out how much ONE liter of paint costs.
Lets gather the information of what we know:
2 1/2 liters of paint
↑ Cost $60.
With the information we know, we can solve to find the answer.
In order to get the answer, we would need to divide 60 by 2 1/2 (or 2.5). We would need to do this because when we divide it, it would allow us to get the cost for 1 liter.
Lets solve:
When you divide, you should get the answer of 24.
This means that one liter of paint cost $24.
$24 should be your FINAL answer.
The demand equation is P = -0.05x + 105

What to find?
<em>The demand equation.</em>
The following information is used to solve the problem.
If (x₁ , y₁) and (x₂, y₂) are any dinstinct points on a line a non-vertical line L, then the equation of the line that has a slope(m) and passes through the point (x₁ , y₁) is given by the formula below:
Assume p, be the unit price and x be the demand when the price is $p.
From the question given, when the unit price x = 300 units, the demand p = $90 and when the unit price x = 1300 units, the demand p = $40
This means the demand curve passes through the points (300, 90) and (1300, 40).
Assume the demand equation is linear, then the line of the equation passes through the points (300, 90) and (1300, 40).
Now;
y=p x₁ =300 y₁ = 90 x₂ = 1300 y₂=40
Substitute the values into the function and simplify.
Simplify the above.
Open the parenthesis.
P- 90 = -0.05x + 15
Add 90 to both-side of the equation.
P = -0.05x + 15 + 90
P = -0.05x + 105
Hence, the demand function is P = -0.05x + 105
