Answer:


Step-by-step explanation:

X+Y = 13

 

$18 + $22 = $258

OR

18X+22Y=258

 

18X + 22(13 - X) = 258

 

18X + 286 - 22X  = 258

 

286 - 4X  = 258

 

-4X= 258 - 286

 

-4X = -28

 

X= 7

Y=6

 7 of the X tour  packages & 6 of the Y tour  packages

How do I find QS here?
docker41 [41]
Answer: 12.

To solve this problem, let's first solve for x. Thi is easiest done by figuring what QR is in terms of x using two equations, both from different lines.

In the first line:
QR = 15 - 4x.

In the third line:
QR = 13x - 1 - x = 12x - 1.

Now, we have to set these equations equal to each other. 
15 - 4x = 12x - 1
15 = 16x - 1
16x = 16
x = 1

Next, we take line three, 13x - 1, and substitute x as 1. The answer is 12.

The cost for Andrea to produce several units of a certain item is $336 plus $12 per unit. She sells this item for $28 per unit.
Morgarella [4.7K]
Profit will be achieved when the money earned is greater than the money spent so,
336 + (n*12) = n*28  any subsequent units sold would result in profit
336 = 28n - 12n
336 = 16n
=>  n = 336/16 = 21
21 units must be sold to draw even any more would result in profit
