Suppose your newspaper is trying to decide between two competing desktop publishing software packages, Macro Publish and Turbo Publish. You estimate that if you purchase x copies of Macro Publish and y copies of Turbo Publish, your company's daily productivity will be U(x, y) =8x0.80.1 + x where U(x, y) is measured in pages per day (U is called a utility function). If x = y = 10, calculate the effect of increasing x by one unit. (Round your answers to two decimal places.) Xpages per day Interpret the result. This means that, if your company now has X copies of Macro Publish and additional copy of Macro Publish will result in a productivity increase of approximately X copies of Turbo Publish, then the purchase of one X pages per day.
