The depth of a lake at a certain point, wich is a function of the distance of that point from shore, is 30 feet.

Find the maximum value of p= 4x + 5y subject to the following constraints :

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3
