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

Answer:
7920 square feet.
step -by- step explanation.
From the the question, the
Length, l= 120 feet.
Width, w= 55% of l
This implies that;
w=0.55×120=66 feet.
Area of rectangle is given by the relation ;
By substitution,
Therefore the area of the rectangular stage is 7920 square feet.
The answer is 63.3
9.5 * 3 + 8.7 * 4 = 63.3
