QD=700-100P+0.5M+30PR
where P is the price of widgets, M is income, and PR is the price of a related (fictional) good, the wodget. Supply of widgets is determined by
QS=900+57.5P
Widgets are _________, and widgets and wodgets are _____________.
a. an inferior good; substitutes.
b. a normal good; substitutes.
c. an inferior good; complements.
d. a normal good; complements.
Assume that M=$61,000 and PR=$250 The equilibrium price of widgets is?
The equilibrium quantity of widgets is?
Now assume two events occur: income falls to $58,000 and supply conditions change such that QS=-300+50P. Solve algebraically for the new equilibrium price of widgets after these two changes.
Solve algebraically for the new equilibrium quantity of widgets after these two changes.
