Mathematics
1 answer:
finlep [7]2 years ago
8 0

Answer:

We have been given the matrix m as m = [874][205].

We can rewrite this matrix as

\begin{gathered}m=\begin{pmatrix}8 &7&4\\2&0&5 \\\end{pmatrix}\\\end{gathered}m=(827045)

Now, we need to the find m_{12}m12

It means we need to find the entity that is present in the first row and the second column.

From the above matrix, we can see that 7 is in the first row and the second column.

Therefore, we have

m_{12}= 7m12=7

At Best Buy they have a stereo system that sells for $2500 and is on sale for 9% and sales tax is 5%. What is the final cost?
Vedmedyk [2.9K]

Answer:

Final cost = $2388.75

Step-by-step explanation:

Cost of stereo system = $2500

Sale = 9%

Cost of sale = 9% of 2500

Cost of sale = \frac{9}{100}*2500 = 0.09*2500

Cost of sale = $225

Price after sale = 2500 - 225 = $2275

Sales tax = 5% of 2275

Sales tax = 0.05 * 2275 = $ 113.75

Final cost = 2275 + 113.75 = $2388.75
