Members of the band are selling candy bars to raise money. The director uses this equation to calculate the amount of profit, p,
ivolga24 [154]

Answer:

<h3>C. 800</h3>

Step-by-step explanation:

Given the equation used to calculate the amount of profit, p, made from selling n candy bars expressed as  p = 1.50n – 500

To find the number of candies sold for $700, we are going to substitute p = $700 into the given expression and find n as shown;

700 =  1.50n - 500

Add 500 to both sides

700+500 = 1.50n-500+500

1200 = 1.50n

Divide both sides by 1.50

1200/1.50 = 1.50n/1.50

800 = n

Rearrange

n = 800

Hence 800 candy bars must be sold to make $700 profit

Question 10. Suppose U and W are subspaces of V, dim V = n, dim U + dim W = n, and U NW = {0}. Prove that V=UW.
Bess [88]

Answer: If the dimension of V is n, then V has n elements.

Now, dim(U) + dim(W) = n, this means that the addition of the dimensions of U and W also has n elements.

and because U and W are subspaces of V, you know that every element on U and W is also an element of V.

If U ∩ W = ∅, means that there are no elements in common between U and W.

Because there are no elements in common, then Dim(U) + Dim(W) = dim(U ∪ W) = n

So U ∪ W has the same number of elements as V, and every element of W and U is also an element of V

this means that U ∪ W = V.
