hello,

i have a little question to ask, so here it is,

"A consumer has £ 60 to spend on purchases of two goods with prices £ 5

and £ 10. If x is the quantity of the first good bought then the quantity of

the second good that can be bought is y = (60 �� 5x)=10 = 6 �� 0:5x. The

consumer0s preferences are represented by the utility function

u(x; y) = ln(x) + 2 ln(y) = ln(x) + 2 ln(6 �� 0:5x)

Find that x which is the global maximum of this function. Justify your

answer."

when i do this question i keep getting a negative answer which seems wrong, people can't buy negative amounts of stuff.

(hello bye the way, its my first post so hello all

)
