[elated to Solved Problem 11A.1 on page 433] Draw an isoquant–isocost line graph to illustrate the following situation: Jill Johnson can rent pizza ovens for $200 per week and hire workers for $100 per week. Currently, she is using 5 ovens and 10 workers to produce 20,000 pizzas per week and has total costs of $2,000. Jill’s marginal rate of technical substitution (MRTS) equals −1. Explain why this means that she’s not minimizing costs and what she could do to minimize costs.
