Answer:
Step-by-step explanation:
Put the side length where x is, then do the arithmetic.
P = 4x
P = 4(5/7) = 20/7
The perimeter is 20/7 units.
Answer:
136 units
65x - 8840
Step-by-step explanation:
Given,
The production cost function is,
Revenue function,
So, profit would be,
P(x) = Revenue - cost
= 260x - 195x - 8840
= 65x - 8840
In break even condition,
Profit, P(x) = 0
65x - 8840 = 0
65x = 8840
⇒ x = 136.
Hence, the break even quantity is 136 units.
