Chapter CR, Problem 43E

Business: approximating cost average. A square plot of ground measures 75 ft by 75 ft, with a tolerance of ± 4 in. Landscapers are going to cover the plot with grass sod. Each square of sod costs $8 and measures 3 ft by 3 ft.

a. Use differentials to estimate the change in area when the measurement tolerance is taken into account.

b. How many extra squares of sod should the landscapers bring to the job, and how much extra will this cost?
