Suppose that Santiago has a utility function for two goods, X and Y, is U(X, Y ) = 4X^.5 + Y (hint: this is an imperfect substitutes utility function). The price of X is $10 per unit and the price of Y is $5 per unit. Suppose that the Santiago has $200 to spend. Solve Santiago’s constrained optimization problem (i. e., what is his optimal bundle?). What is his level of utility at the optimal bundle?

250

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
