To solve this problem, we need to determine the value of x, which represents the number of legs each office chair has.
Let's break down the information given:
Number of office chairs: 80
Number of legs per office chair: x
Number of round tables: 20
Number of legs per round table: 3
Total number of legs remaining: 300
We can set up the equation as follows:
(Number of office chairs - (40% of Number of office chairs)) * Number of legs per office chair + Number of round tables * Number of legs per round table = Total number of legs remaining
(80 - 0.4 * 80) * x + 20 * 3 = 300
Let's simplify and solve for x:
(80 - 0.4 * 80) * x + 20 * 3 = 300
(80 - 32) * x + 60 = 300
48 * x + 60 = 300
To isolate x, we subtract 60 from both sides of the equation:
48 * x + 60 - 60 = 300 - 60
48 * x = 240
To solve for x, we divide both sides of the equation by 48:
x = 240 / 48
x = 5
The value of x is 5.
#### 5
The answer is: 5
