Answer:

1. Sean

2. Mariana

Equations:

Sean: y=-5.5x+300

Mariana: t=-5x+250

For the first question, it is basically asking for who has a greater negative slope, which would be Sean, since he drank his faster.

For the second question, Mariana finished his slushy at the x-intercept of 50, while for Sean, it would be an estimated 54.5.
