Answer:
n = 120i + 310j + 60k
p = 29i + 18j + 21 k
Total cost = $10,320
Step-by-step explanation:
Let n and p represent the vectors for number of products and prices respectively.
Also, the coordinates i,j and k represent cashews, walnut and Brazil nut respectively.
The vector form of the total number of bags ordered and the cost are;
n = 120i + 310j + 60k
p = 29i + 18j + 21 k
We can obtain the total cost by obtaining the dot product of the two vectors.
Total cost = n.p = (120i + 310j + 60k).(29i + 18j + 21 k)
C = 120×29 + 310×18 + 60×21
C = $10,320
Here we must see which information about the graph of a linear relationship is given. The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

Linear relationships:</h3>
So we define a general linear relationship as:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this problem we know that:
- Originally, the sheet of ice is 2 meters thick.
- The thickness decays at a constant rate
- After 3 weeks, the thickness is 1.25 meters.
The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)
So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.
