Sharlise bought a commuter pass and after riding 3 days to and from scool the pass is worth $22.40. After 6 days of riding to and from school the pass is worth $12.80. Rosa pays $50 for an unlimited rides monthly pass lasting 30 days? Can the monthly cost of these students' bus fares be modeled by the same linear equation? Explain why or why not?
Which "same linear equation"?
($22.40 - $12.80)/6 = $1.60/day
$1.60 * 30 = $48.00
