Refer to matrix A and identify the matrix element a31.

Blizzard [7]

<h3>Answer: D) 7</h3>

===================================================

Explanation:

a31 means "the value in the third row, first column". That value is 7

As another example, a22 = 3 since 3 is in the second row, second column.

Another example: a12 = -1 because we're in the first row and second column.

This is a 3x2 matrix due to it having 3 rows and 2 columns.

solmaris [256]

You must go to the water park for 8 days to make buying the season pass worth it.

<em><u>Explanation</u></em>

Suppose, the number of days you must go to the water park is $x$

Admission for the park is 17.50 per day. So, <u>the total cost for $x$ days</u> will be: $17.50x$

Given that, the season pass cost 125. So, the equation will be.....

$17.50x=125\\ \\ x=\frac{125}{17.50}=7.142...\\ \\ x \approx 8$

<em>(As the number of days can't be in decimal)</em>

So, you must go to the water park for 8 days to make buying the season pass worth it.
