A measure of the adhesiveness of honey can be modeled as

f(x, y) = -125.48 + 4.26x + 4.85y — 0.05x ² — 0.14y ²

where x is the percentage of glucose and maltose and y the percentage or moisture. t

(a) Calculate the absolute maximum of the adhesiveness of honey. (Round your answer to one decimal place.)

(b) If FDA restrictions for Grade A honey require that the combined percentages of glucose, maltose, and moisture not exceed 57%, what is the maximum measure of adhesiveness possible? (Round your answer to three decimal places,)
