Hello i'm currently studying economics and i have difficulties doing this exercice.

Suppose to produce cars a company requires both lappnuworkers) and energy (electricity). The cost to employ one worker (w) is El 0 and the cost for one unit of electricity (p) is 20. Suppose the company has fourldifferent technologies to produce 100 cars: Technology # units of # units of workers electricity A 1 8 B 3 5 C 4 7 D 8 3 1. Write down the equations for the ISO cost lines passing through technologies A,B,C & D. (Use the number of units of electricity as your variable on the left of the equal sign and the number of units of workers as your variable on the right.) (2 pts.) 2. What technology should the rm use and why? (1 pts.) 3. Draw the ISO cost lines for technologies ADC & D on a graph with # units of workers (L) on the Xaxis and # units of electricity (R) on the Yaxis. 4. Suppose firms only have technology A and D available. Keeping the price of electricity fixed, what must be the price of Lam to make the rm indifferent between technologies A & D
