Answer:
The indifference point is 100 minutes.
Step-by-step explanation:
Giving the following information:
Plan a cost $23 plus an additional $.08 for each minute of calls.
Plan B cost $19 an additional $.12 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
Plan A= 23 + 0.08*x
Plan B= 19 + 0.12*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
23 + 0.08x = 19 + 0.12x
4 = 0.04x
100= x
The indifference point is 100 minutes.
<u>Prove:</u>
Plan A= 23 + 0.08*100= $31
Plan B= 19 + 0.12*100= $31
The answer is -4. your welcome.
Answer:
A=90
Step-by-step explanation:

Answer:
776 times
Step-by-step explanation:
- Find out how far a mile is in inches -> 1 mile = 63360 inches.
- Find out the circumference of the wheel (how far it will travel per revolution) C = πd = 26π = 81.68 inches.
- Divide the total distance by how far we go each revolution: 63360/ 81.68 = 775.71 revolutions.
- Therefore to the nearest revolution, the wheel turns 776 times.
