Answer:
33 and -39
Step-by-step explanation:
Angle on a straight line = 180
|5x + 15| = 180 and |5x + 15| = -180
5x + 15 = 180
Subtract 15 from both sides;
5x = 165
Divide both sides by 5;
x = 33
5x + 15 = -180
Subtract 15 from both sides;
5x = -195
Divide both sides by 5;
x = -39
Answer:
The indifference point is 8 weeks.
Step-by-step explanation:
<u>First, we establish the total cost formula for each:</u>
x= number of weeks
Club:
Total cost= 20 + 15*x
Retail:
Total cost= 17.5*x
<u>Now, we equal both formulas and isolate x:</u>
20 + 15x = 17.5x
20 = 2.5x
8=x
The indifference point is 8 weeks.
<u>Prove:</u>
Total cost= 20 + 15*8= $140
Total cost= 17.5*8= $140
D. people do not have to have a good or service that another person wants
Reason: Money gives people a universal unit of value. For example, If I needed a toothbrush and I have a pair of scissors, In order for me to get a tooth brush is to trade my scissors with someone else who has a tooth brush and wants scissors. As you can see, this isn't practical. If I had money, I will only need to find someone who has a tooth brush.
I can’t understand the question can you write it more clearly?
