An orange grower has discovered a process for producing oranges that requires two inputs. the production function is q = min{2x1, x2}, where x1 and x2 are the amounts of inputs 1 and 2 that he uses. the prices of these two inputs are w1 = $5 and w2 = $2, respectively. the minimum cost of producing 140 units is therefore

a. $980.
b. $630.
c. $1,400.
d. $280.
e. $700.

Six years ago, an 80-kw diesel electric set cost $160,000. the cost index for this class of equipment six years ago was 187 and is now 194. the cost-capacity factor is 0.6. the plant engineering staff is considering a 120-kw unit of the same general design to power a small isolated plant. assume we want to add a precompressor, which (when isolated and estimated separately) currently costs $13291. determine the total cost of the 120-kw unit. (hint: skip $ and comma symbols)
