To distinguish between the different parts of functions and function calls.

Below is a program that uses a function to compute the cost of leaving dogs at Joey$$s Doggy Day Care.

There is a cost per dog that is charged daily.

$1$ def day$\_$care$\_$cost $($ number$\_$of$\_$dogs $,$ number$\_$of$\_$days $,$ price$\_$per$\_$dog $)$:

$2"""$

$3$ Computes the total cost of a stay at Doggy Day Care

$4$

$5$ number$\_$of$\_$dogs : the number of dogs

$6$ number$\_$of$\_$days : duration of stay in days

$7$ price$\_$per$\_$dog : cost for a single dog in dollars

$8$

$9$ Returns : total cost of the stay

$10"""$

$11$ daily$\_$dog$\_$cost $=$ number$\_$of$\_$dogs $*$ price$\_$per$\_$dog

$12$ total$\_$cost $=$ daily$\_$dog$\_$cost $*$ number$\_$of$\_$days

$13$ return total$\_$cost

$14$

$15$ # compute the cost of a stay for $3$ dogs

$16$ # staying $7$ days at a rate of $$49\mathrm{.}50$ per dog

$17$ first$\_$stay $=$ day$\_$care$\_$cost $(3,7,49\mathrm{.}50)$

$18$

$19$ # compute the cost of a stay for $10$ dogs

$20$ # staying $3$ days at a rate of $$19\mathrm{.}75$ per dog

$21$ second$\_$stay $=$ day$\_$care$\_$cost $(10,3,19\mathrm{.}75)$

For each of the following terms, list ALL of them that you can find in this source code, along with their line

numbers. Submitting a screenshot where you have clearly identified these elements is also acceptable.
