Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item.
<u>The net income formula:</u>
y= (5 - 4)x - 120
(5-4)= contribution margin per unit sold (x)
120= fixed costs
<u>To calculate the break-even point in units, we need to use the following formula:</u>
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 120 / 1
Break-even point in units= 120 units
Prove:
y= 1*120 - 120
y= 0
Answer:
Step-by-step explanation:
From the given figure it is clear that we two rays because both sides have one endpoint and goes on infinitely in only one direction.
If a ray has end point at A and goes on infinitely in only one direction towards point B, then ray is denoted as 
.
For first side, we have point V as end point and ray goes goes on infinitely in only one direction towards point U. So, first side is 
.
For second side, we have point V as end point and ray goes goes on infinitely in only one direction towards point W. So, second side is 
.
Therefore, the sides are .
First, let's write two expressions, letting x= the number of months which have elapsed:
Bill: 120 + 10x
Phil: 150 + 4x
If we set them equal to each other, then solve for x, that will be the number of months where their weights equal each other:
120+10x = 150 + 4x [starting equation]
-120 -4x -120 -4x [ subtract 120 from both sides, and 4x from both sides, to isolate the term with the variable]
<u>6x</u> = <u>30</u> [divide both sides by 5]
5 5
x=6. They will weigh the same in six months.
