I would say you are more likely to have complex roots. If you think of graphs of polynomials, if you draw a function that doesn't pass through the x-axis, all roots are complex.
If you look through the chart, you'll see that in each column,
the amount of money donated is 1/5 the number of lunch
specials sold.
The equation is:
Donation amount = (1/5) · (lunch specials sold) .
The constant of proportionality in money per lunch special sold
is $1/5 or 20 cents.
