Plan A- $10 regardless of miles
Plan B- $2 per mile
Plan C-$5 plus $.50 per mile
Which plan is better? Why? Give three justifications (graph, table, equation)
Equations-
Plan A- $10
Plan B- 2x=n (x=miles, n=$)
Plan C- Miles x .50= $
What characteristics will be in all linear equations?
-a constant of proportionality (multiply it by the independent variable)
-An equations that works for everything in the pattern (pos, neg, even, odd)
- Dependent variable = (indep. variable) (constant of proportionality)
-Amount $= (miles walked) x (4)
-unit rate***
Class is not entirely firm on these ideas.
