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
i hope it will help you!
Answer
60
Step-by-step explanation:
A triangle is 180 degrees. So first since you have one of the degrees you will do 180-60=120. Since the 2 ys are the same you can just divide 120 by 2. Which is 60. So y=60

Answer:
25x^2 - 16.
Step-by-step explanation:
(5x+4)(5x-4)
F = 5X*5X = 25X^2
O = 5x * - 4 = -20x
I = 4 + 5x = 20x
L = +4 * -4 = -16
So its
25x^2 - 20x + 20x - 16
= 25x^2 - 16.
