Answer:
At break even cost = revenue
Step-by-step explanation:
A company is said to be at break even if the cost of producing an item is equal to the revenue generated from the sell of that item, that means there is no loss or gain.
If the cost function C(x) = 200 + 10x and the revenue function R(x) = 60x - x², where x is the amount of items produced. At break even, R(x) = C(x)
60x - x² = 200 + 10x
x² - 60x + 10x + 200 = 0
x² - 50 x + 200 = 0
x = 46 or x = 4 is the break even point
<em><u>Question:</u></em>
A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32
<em><u>Answer:</u></em>
Option D
Each lot weight
part of pound
<em><u>Solution:</u></em>
Given that,
A jeweler is dividing 3/8 of a pound of rubies among 4 lots
To find: part of a pound each lot weigh
From given,

Let "x" be the part of a pound each lot weigh
Therefore,

This forms a proportion and solve by cross multiplying

Thus, each lot weight
part of pound
Let call the number we are searching for x. 2*x + 17 = -1 so 2*x = -1-17 = -18 and x = -18/2 = -9
The answer is A:
Because the only difference between the rest of the answer choices are the lower and upper quartiles, that is all you need to find. In order to do so you find the median for the first half (lower quartile) and then find the median for the second half. In this case it is 29 (Q1) and 58 (Q2)
