it says that at an output of 100, the firm uses three units of capital (K) and 7 units of labor (L). In 1 capital is $100 per unit per day and labor is $80 per worker per day. So you have 100x 3= $300 and then you have 7x$80=$560. Add those together and at a daily output of 100, the cost for technology one would be $860. See how I did that? Now do that for each technology at each output level.
