Samantha wants to use her savings of $1150 to buy shirts and watches for her family. The total price of the shirts she bought wa

irakobra [83]

The cost of the shirts is stable, so we can subtract $1150 - $84, which = $1066. Now we want to find how many watches we can buy with $1066, or how many times $99 fits into $1066. So divide 1066 by 99 to get 10.77. You can't buy 77ths of a watch, so round it down to 10 and you have your answer. Samantha can buy 10 watches.

Step-by-step explanation:

8n=-3m+1

-3m+1=8n

-3m=8n-1

3m=-8n+1

m=(-8n+1)/3 or (1-8n)/3

The matrix equation that could show the total books is $\left[\begin{array}{cc}7&1\\2&6\end{array}\right] + \left[\begin{array}{cc}4&3\\6&1\end{array}\right] = \left[\begin{array}{cc}11&4\\8&7\end{array}\right]$

<h3>How to determine the matrix equation?</h3>

The given parameters are the two-way tables attached to the question.

From the tables, we have the following matrices

$June = \left[\begin{array}{cc}7&1\\2&6\end{array}\right]$

$July = \left[\begin{array}{cc}4&3\\6&1\end{array}\right]$

The sum of these matrices is represented as:

June + July = Total

So, we have:

$\left[\begin{array}{cc}7&1\\2&6\end{array}\right] + \left[\begin{array}{cc}4&3\\6&1\end{array}\right]$

Add the elements at corresponding positions

$\left[\begin{array}{cc}11&4\\8&7\end{array}\right]$

Hence, the matrix equation is $\left[\begin{array}{cc}7&1\\2&6\end{array}\right] + \left[\begin{array}{cc}4&3\\6&1\end{array}\right] = \left[\begin{array}{cc}11&4\\8&7\end{array}\right]$
