Question

A clerk counted 14 small baseball caps, 37 medium baseball caps, and 29 large baseball caps on the store shelves. She also counted 9 small baseball caps and 19 medium baseball caps in the stockroom.

A) Organize the data in a matrix. Name the matrix B. Label the rows and columns.

B) Each baseball cap sells for $16. Create the matrix that shows the total value of each cap size in each location.

I've already done A http://i.imgur.com/3HrDSsp.png

Could someone help me with B?

Answer 1

I have done A, just need help with B

Answer 2

Two ways to do this.
First way:
organize columns into one for small, one for medium, and one for large.
Organize rows into one for store, one for stock room.
It should look like this
5 4 9
2 3 6
This is a 2x3 matrix.
The other way is to use columns for location, and rows for size.

Answer 3

Hey, this is my answer for A http://i.imgur.com/3HrDSsp.png

Answer 4

How would I draw B?

Answer 5

?

Answer 6

For some reason, the image is blank, or my connection is extremely slow.
Anyway, you need to multiply the number of caps at each location by 16, add them up and give the total.
The resulting matrix should have two values, in the same direction (row or column) as you had it in part A.

Answer 8

So I add 16 to every number?

Answer 9

Multiply. If there are 4 caps, you write 4*16=64.

Answer 10

So for A my matrix has two tables.
In the shelves part I have 14, 37, 29

Answer 11

To get my Part B answer I multiply each one by 16?
So it would look like:

Shelves: 224, 592, 464

Answer 12

??

Answer 13

I still cannot see your matrix.
Does it have two rows or three rows?

Yes, add them up for the store inventory.
Do the same for the stock room inventory.
