To compare: the point totals as a function of rank for quarterbacks and running backs.
Passers produced more points than runners when ranked from first to about twentieth. The points decrease more rapidly for passers as rank changes than for runners, so as rank changes further the runners will produce more points.
Given information:
The given equation is
Concept Used:
Substitution means replacing the variables (letters) in an algebraic expression with their numerical values.
Calculation:
Calculate the points for the passer when his rank
Rank | Points for passer | Points for runner |
1 | 475 | 400 |
10 | 222 | 200 |
20 | 145 | 140 |
30 | 101 | 110 |
40 | 69 | 85 |
50 | 45 | 65 |
Observe and compare points for passers and runners of the same rank.
When the rank is 1-20, the passer produced more factory points than the runner. As the ranking falls further down (30 and beyond), the runner produces more points. The points decrease more rapidly for passers as rank changes than for runners.
