Answer:
minimum of 13 chairs must be sold to reach a target of $6500
and a max of 20 chairs can be solved.
Step-by-step explanation:
Given that:
Price of chair = $150
Price of table = $400
Let the number of chairs be denoted by c and tables by t,
According to given condition:
t + c = 30 ----------- eq1
t(150) + c(400) = 6500 ------ eq2
Given that:
10 tables were sold so:
t = 10
Putting in eq1
c = 20 (max)
As the minimum target is $6500 so from eq2
10(150) + 400c = 6500
400c = 6500 - 1500
400c = 5000
c = 5000/400
c = 12.5
by rounding off
c = 13
So a minimum of 13 chairs must be sold to reach a target of $6500

12x-3x=9x 9+7=16
9x+16=25x
K=2, because the bottom of the parabola shifted to the x value 2 from 0.

21 is the real answer
because of BODMAS
Answer:
5x - 5
Step-by-step explanation:
Allison: 9x
Adrian: 4x - 5
To find the difference, we subtract Adrian's number of miles, 4x + 5, from Allison's number of miles, 9x.
9x - (4x + 5) =
We think of the negative sign to the left of the parentheses as a -1, and we distribute it by multiplying -1 by 4x and multiplying -1 by 5.
= 9x -1(4x + 5)
= 9x - 4x - 5
Now we combine like terms. The only like terms are 9x and -4x.
= 5x - 5
