Question

Suppose the price of a gallon of ice cream rises from $4 to $5 and the price of coffee rises from $2 to $2.50 . If the CPI rises from 150 to 200 people will likely buy

a. more ice cream and more coffee. b. more ice cream and less coffee. c. less ice cream and more coffee. d. less ice cream and less coffee

Answer #1

Since price rises by 33% on an average whereas ice cream price rises by 25% and coffee price rises by 25%.

An ice cream scoop holds a normally distributed mass of ice
cream with an average of 68 g and variance of 16 g2 . In the
freezer I have a 2 gallon bucket of ice cream4 . Because at such
large volumes the dispensing process is inaccurate, the 2-gallon
buckets also have a normally distributed mass with a mean of 4500 g
and a standard deviation equal to 5% of the mean. 15. On Sunday, I
make myself a 3-scoop...

vanilla?
(b) What is the probability that 12 or more...

Suppose the market demand function for ice cream is
Qd = 10 - 2P and the market supply function for ice
cream is Qs= 4P - 2, both measured in millions of
gallons of ice cream per year. Suppose the government imposes a
$0.50 tax on each gallon of ice cream produced. The price received
by sellers with the tax is:
$2.33.
$1.50.
$1.73.
$1.83.
