Answer:
ok hi 4___________$_______
First, lets determine the regular price of his purchase :
16.99 (3) + 34.99 (3) + 52.99 (2) + 5.99 (5) = 50.97 + 104.97 + 105.98 + 29.95 = 291.87
Therefore, the regular price of his purchase is $291.87 before sales tax.
If he receives 25% off of his total purchase, then the price is now :
291.87 * .75 = $218.90
We multiply by 75% because we are only paying 75% of the total purchase price since we received a 25% discount.
The total savings is
291.87 - 218.90 = $72.97
If sales tax is 10%, the total purchase price after sales tax is :
218.90 * 1.10 = $240.79
The sales tax is $21.89 since
240.79 -218.90 = 21.89
If he pays with 3 $100 bills, we should receive :
300 - 240.79 = $59.21
in change.
If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12.
My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.

Given system of linear equations are ,
And we need to find the Solution of the linear equation . So let's Firstly number the equations .
<u>→</u><u> </u><u>Multipl</u><u>ying</u><u> </u><u>equⁿ</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>by</u><u> </u><u>3</u><u> </u><u>,</u>
=> 3 ( x + y ) = 2*3
=> 3x + 3y = 6
<u>→</u><u> </u><u>Addin</u><u>g</u><u> </u><u>the</u><u> </u><u>two</u><u> </u><u>equations </u><u>,</u><u> </u>
=> 3x + 3y -3y + y = 6 + 2
=> 4y = 8
=> y = 8/4
=> y = 2
<u>→</u><u> </u><u>Put</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>2</u><u> </u><u>in</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>,</u>
=> x + y = 2
=> x + 2 = 2
=> x = 2- 2
=> x = 0

the required solution is ( 0 , 2 ) .</u></h3>
