A college employs 15 stewards. What is the average monthly wage of the stewards if the college pays 226.20 in wages each month?

madreJ [45]

<h2>Answer:</h2>

$15.08

<h2>Step-by-step explanation:</h2>

As the value 226.20 is the total of all wages, you can work out the mean.

Mean averages are usually worked out as the total / number of values.

Because you already know the total is 226.20 and the number of values is 15 different wages, divide 226.20 by 15 to get $15.08.

3. You sell storm windows and doors. You receive a straight

OLEGan [10]

Answer:

$\$3886.8$

Step-by-step explanation:

Commission received on selling each storm window $=8\%$ of the selling price of each storm window

Commission received on selling each door $=12\%$ of the selling price of each door

Amount earned on selling storm windows = $5,400

Amount earned on selling doors = $28,790

Commission received on selling storm windows $=\frac{8}{100}(5,400)=\$432$

Commission received on selling doors $=\frac{12}{100}(28,790)=\$3454.8$

Therefore,

Total commission received $=432+3454.8=\$3886.8$

Three times the second of three consecutive even integers is twelve less than twice the sum of the first and third integers.Find

Tresset [83]

Answer:

The largest even integer is <u>14</u>.

Step-by-step explanation:

Given:

Three times the second of three consecutive even integers is twelve less than twice the sum of the first and third integers.

Now, to find the largest even integers.

As, 2 is an even number.

Let an even integer be $2x.$

So, the three consecutive even integers are:

$2x,\ 2x+2,\ and\ 2x+4.$

Now, we have to add two to get next even number.

Thus, 3 times the second one of these is:

$3(2x + 2) \\= 6x + 6$

Now, the sum of the first and third ones are:

$2x + 2x + 4 \\= 4x + 4$

So, the twice the sum of the first and third integers is less than twelve:

$2(4x+4)-12\\=8x+8-12\\=8x-4$

Now, 3 times the second is 12 less than twice the sum of the other two:

$6x+6=8x-4$

<em>Getting the variables on one side and the number on other:</em>

$6+4=8x-6x$

$10=2x$

<em>Dividing both sides by 2 we get:</em>

$5=x$

$x=5.$

Now, the even numbers we get are:

$2x=2\times 5=10\\2x+2=2\times 5+2=10+2=12\\2x+4=2\times 5+4=10+4=14.$

<em>Thus, the third number is the largest number which is 14.</em>

Therefore, the largest even integer is 14.
