fill in the blanks - this is subject in microeconomic class
profit table - please show me how to calculate below step by step
QTY | TR | TC | PROFIT | MR | MC |
0 | 0 | 50 | - | - | |
1 | 50 | 10 | |||
2 | 90 | 75 | |||
3 | 120 | 23 | |||
4 | 140 | 122 | |||
5 | 150 | 10 | 30 |
TR=Price*QUantity
Price =a-bQ now if Q=1
Price=a-b
Revenue=(a-b)*Q=a-b
When Q=2 then P=a-2b
Revenue=(a-2b)*2=2a-4b=90
a-2b=45
When Q=3
Revenue=Price*Quantity=(a-bQ)*Q=(a-3b)*3=120
a-3b=40 then solving these 2 equations we get b=5 and a=55
TR=55-5Q
Total Cost=c+dQ
When Q=0
Total Cost=FIxed Cost=50
When Q=2
TC=50+2d
When Q=4
TC=50+4d
2d=47
d=23.5
TC=50+23.5d
MR =TR2-TR1/1 and MC=TC2-TC1/1
Q | TR | TC | Profit=TR-TC | MR | MC |
0 | 0 | 50 | -50 | - | - |
1 | 50 | 60 | -10 | 50 | 10 |
2 | 90 | 75 | 15 | 40 | 15 |
3 | 120 | 97 | 23 | 30 | 22 |
