ANSWER
a relation only
EXPLANATION
The given graph shown in the attachment represents only a relation and not a function.
The reason is that, a vertical line drawn across this graph will intersect this graph at more than one point.
Since the graph fails to pass the vertical line test, the ordered pair represented by this graph represents a relation only.
5 times 10.50 = $52.5
An additional $45
3 times 22 = $66
An other additional $65
The total price her shopping list costs is 229.5
