Sharon has the following utility function: U (X,Y)= sqrt(X)+sqrt(Y) where X is her consumption
of candy bars, with price Px=$1 , and Y is her consumption of espressos, with price Py= $4 .
a. Derive Sharon’s demand for candy bars and espressos.

A. X=0.906I and Y=1.456I

B. X=1.352I and Y=1.456I

C. X=0.800I and Y=0.050I

D. X=1.241Iand Y=1.929I

E. X=0.157I and Y=0.050I

b. Assume that her income is I=$100 . How many candy bars and espressos will Sharon consume?
c. What is the marginal utility of income
