Discuss whether it is possible that any devices if the production cost is R0,00

suppose tasty treat wants to introduce two new items in its menu: milkshake and smoothie. The cost to make a single serving of milkshake and smoothie is $60 and $50 respectively. They wants to minimize their cost. Everyday, at least 25 watts of electricity should be used in the kitchen. To make one serving of milkshake and smoothie, 1 watt and 2 watts of electricity is required, respectively. 3 minutes and 2 minutes are required each day to produce a serving of the items using at least 48 minutes by the workers.

Solve the differential equation 

dy/dx=x/16y

.

a) Find the implicit solution

b) Find the equation of the solution through the point (x,y)=(4,1) Your equation must describe a single curve of y=f(x) with the domain of f as large as possible. 

c) Find the equation of the solution through the point (x,y)=(0,−2) Your answer should be of the form y=f(x)
