Greetings from Brasil...

Observing the arrangement of the points, we notice that a line is the closest to this grouping. Tracing the line between the points (blue line) - refer to attached

We note that zero people at home will not spend any amount, so the first point will be (0; 0).

After the straight line and the alternatives of the question, we can say that for 8 people there is a cost of

$250

(each vertical division (Y-axis) is equivalent to $20)
