Answer: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x represent the total dollar amount of phone sales that she makes.
Let y represent the the total dollar amount of computer sales that she makes.
Josiah earns a 2% commission on the total dollar amount of all phone sales he makes, and earns a 7% commission on all computer sales. She earned a total of $156 in commission. This means that
0.02x + 0.07y = 156 - - - - - - - - - - -1
Josiah had $300 more in computer sales than in phone sales. This means that
y = 300 + x
Answer:
29.79 should be the answer
Step-by-step explanation:
200 copies 19.50 + 9.00 for 100 copies = 28.50 + 4% = 29.79
2,100,000 millimeters
1 meter = 1000 <span>millimeters</span>
300 X 7 = 2100
7 days in a week
2100 X 1000 = 2,100,000
A 2 x 2 matrix has 2 rows and 2 columns
A specific 2 x 2 matrix a with no zero entries at all is ![\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%26-2%5C%5C-3%266%26%5Cend%7Barray%7D%5Cright%5D)
<h3>How to construct the matrix?</h3>
From the question, we understand that the matrix is a 2 x 2 matrix.
A 2 x 2 matrix is represented as:
![\left[\begin{array}{cc}a&b\\c&d&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%26b%5C%5Cc%26d%26%5Cend%7Barray%7D%5Cright%5D)
Also from the question we understand that the elements of the matrix are non-zero.
This means that:
An example of such matrix is:
Note that there are several matrices that fit the given construction requirement
