K=2/9 is the answer because multiple both sides by 2 then you get k-10k+6=8 then subtract -10k from k you get -9k+6=8 then do 6-8 with that answer do -9k=2 then divide both sides by -9

Your furniture store sells two types of dining room tables. The first, type A, costs $210 and you make a $21 profit on each one.
zimovet [89]

<u>Answer</u>

In order to minimize total cost sell A type 40 numbers and B type 90 numbers

<u>Solution</u>

furniture store sells two types of dining room tables.  

The first, type A, costs $210 and you make a $21 profit on each one.  

The second, type B, costs $180 and you make a $20 profit on each one.  

We can order no more than 130 tables this month, and you need to make at least $2640 profit on them.

Let x be the number table  Type A sold, type B sold = 130-x

To find the value of x

21x +(130-x)20=2640

solving we get x=40

There are two possibilities

1)

A type sold =40 B type sold = 130 - 40 =90

total cost = 40 x 210 +  90 x 180 = 24600

2)

A type sold =90 B type sold = 130 - 90 =40

total cost = (90 x 210) + (40x180)=26100

In order to minimize total cost, choose first possibility

sell A type 40 numbers and B type 90 numbers
