Answer:
Option B
Step-by-step explanation:
-1/2x≥4
1) Multiply both sides of the inequality by the reciprocal of -1/2: (-2)
x≤-8
Graph x≤-8 as a line. Remember that lesser negative values go to the left!
ALSO don't forget when you multiply both sides of an inequality by a negative number the inequality sign flips.
Answer:
t=p-r-s
Step-by-step explanation:
just bring r and s to the other side
X+23=2X+4
X-2X=4-23
-x=-19
X=19
You didn’t not show what is the relation between the expressions so I assumed it’s equall
Answer:
a) 50S + 30C ≤ 800
b) 1) MAX = S + C
2) Max = 0.03S + 0.05C
3) Max = 6S + 5C
Step-by-step explanation:
Given:
Total space = 800 square feet
Each sofa = 50 square feet
Each chair = 30 square feet
At least 5 sofas and 5 chairs are to be displayed.
a) Write a mathematical model representing the store's constraints:
Let S denote number of sofas displayed and C denote number of chairs displayed.
The mathematical model will be:
50S + 30C ≤ 800
At least 5 sofas are to be dispayed: S ≥ 5
At least 5 chairs are to be displayed: C ≥ 5
b)
1) Maximize the total pieces of furniture displayed:
S + C = MAX
2) Maximize the total expected number of daily sales:
MAX = 0.03S + 0.05C
3) Maximize the total expected daily profit:
Given:
Profit on sofas = $200
Profit on chairs = $100
Max Expected daily profit =
Max = (200S * 0.03) + (100C * 0.05)
<em>Max = 6S + 5C</em>
