SUPPOSE THE DEMAND FOR GOOD X ISGIVEN BY QDX =10-2PX+PY+M. THE PRICE OF GOOD X IS $1, THE PRICE OF GOOD Y IS $10 AND THE INCOME IS 100. GIVEN THESE PRICES AND INCOME, HOW MUCH GOOD X WILL BE PURCHASED.

A. 1000

B. 515

C. 115

D NONE OF THESE

QDx = 10-2Px+Py+M, where Px is given as $1, Py = 10 and M = 100

Just plug in these values into the given equation

=10 - 2*1 + 10 + 100

=118

So the correct option is \"None of These\"
