Step-by-step explanation:</h2>
Relation--
A relation from a set A to set B is the set of all the ordered of the type:
(a,b) where a belongs to A and b belongs to B.
if A has m elements and B has n elements.
Then the total number of relation from A to B are:
Function--
A function from a set A to set B is the set of all the ordered pair where each element of set A is mapped to a single element of the other set.
i.e. every element has a single image.
if A has m elements and B has n elements.
Then the total number of functions from A to B are:

Answer:
Dan has $7 and Julio has $12
Step-by-step explanation:
Julio = x
Dan = y
They both have a total of $19:
x + y = 19
Julio has 5 more dollars than Dan:
(Therefore Dan would need 5 more dollars to catch up to what Julio has)
y + 5 = x
We now plug in one equation into the other and get:
y + (y+5) = 19
2y+5 = 19
2y = 14
y = 7
Plug in Dan's amount into the initial equation and we get:
7+5 = x
x =12
