Answer:
5400
Step-by-step explanation:
Let x represent the cost of a chair and y represent the cost of a table. We can use this to set up a system of equations:
7x=2y
6x+5y=10575
We can solve this system using substitution.
Start by rewriting the first equation in terms of x.
Substitute this into the second equation:
Multiply both sides by 7
Divide both sides by 47
This means...
Divide both sides by 7
One chair costs 450. Now, multiply this number by 12 to find the cost of 12 chairs.
12 chairs cost 5400.
L represent Option A. The correct answer is that the mixture has the intended volume and has more than the intended percent of butterfat.
<h3>What is the graph about?</h3>Note that:
The graph shows that the point L is one that is below the blue line of the graph.
Therefore, x + y = 500
Also one need to see that:
0.18x + 0.04y = 500(0.12)
Since that cream is 18% butterfat, milk is 4% butterfat, so L is composed of of 350 ml of cream and 100 ml of milk.
Hence the total amount of butterfat for L is:
0.18 x 350 + 0.04 x 100
= 67ml.
Next, one has to calculate 12% of the volume of L :
12% of 450:
0.12 x 450 = 54ml
So, because 67 is bigger than 54, this implies that the volume of butter fat in L is more than 12 %.
