Answer:
For more than 180 minutes of phone use.
Explanation:
Let m represent number of minutes of phone use in a month.
We have been given that in Plan A, there is no monthly fee, but the customer pays $0.06 per minute of use.
The cost of using m minutes in plan A would be
.
We are also told that in Plan B, the customer pays a monthly fee of $4.80 and then an additional $0.03 per minute of use.
The cost of using m minutes in plan B would be
.
To find the amounts of monthly phone when Plan A will cost more than Plan B, we will set cost of plane A greater than cost of plan B as:

Let us solve for m.




Therefore, Plan A will cost more than Plan B for more than 180 minutes of phone use.

Answer:
The correct answer here to the first fill in the blank is Increase and for the second one it is Upward and for the third one it is Rightwards.
Explanation:
If there is any change in the interest rate or tax treatment , there will be an impact on the capital utilization , which will then help in determining the positions of the LRAS (long run aggregate supply curve ) curve. So if there is an decrease in the interest rate , then it will cause increase in the capital utilization, which will then shift the production to upwards and there by shift the LRAS curve rightwards. LRAS curve shifts to rightwards when in the long run , increase in investment ( which is due to lower interest rate ) causes the economy's capacity to produce, as the production cost is reduced.
