If Avery is willing to pay $10 for a pizza, Pia is willing to pay $13, and Sylvio is willing to pay $15, how much consumer surpl
Mrrafil [7]

Answer:

$4

Step-by-step explanation:

Total consumer surplus is given by the difference between the willingness to pay of each customer to the actual price of a good.

Since Avery is only willing to pay $10 and the pizza costs $12, Avery will not buy a pizza and should not be considered for consumer surplus.

Since Pia is willing to pay $13, and Sylvio is willing to pay $15, consumer surplus is:

S = (\$13-\$12)+(\$15-\$12)\\S=\$4

When the price of pizza is $12, a consumer surplus of $4 is achieved.

A thief steals an ATM card and must randomly guess the correct five-digit pin code from an 8 key keypad repetition of digits is
Rus_ich [418]

Answer:

1/32768

Step-by-step explanation:

We have 5 digit pin code plots and 8 choices per slot. Because repetition is allowed (1 digit can have 8 choices) so we multiply out the number of choices per slot . Hence:

8*8*8*8*8 = 8^{5} = 32768

So there are 32768 different combination.

But correct guess on the first try is just only 1 time, so its' probability:

1/32768
