1- multiply bottom equation by -3

3x+3y=27
-3x+111= 33

111+3y=60
3y=60-111
3y= -51
y= -17

Replace y in first equation with -17
3x+3(-17)= 27
3x-51=27
3x=27+51
x=26

Here, rest of them in the pic..

16,000 rolls of paper were purchased and 12,500 were sold at $1.79, what is the total ending inventory?
Maslowich
12,500 x 1.79 to find the price but 16,000 - 12,500 to get how many were left. 
12,500 x 1.79 = $22,375 that they made from selling. 16,000 - 12,500 = 3,500 rolls left in the inventory. This question confused me so I just gave both answers.

10 % off the regular price. what is the discount amount any price?
zloy xaker [14]

Answer:

Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9

EX: item cost $100

$100 x 0.9 = $90

Meaning the price of the item after the discount is applied would be $90
