Question

Sean and Mariana started drinking their slushies at the same time and tried to drink them as fast as they could.

Sean started with 300300300 milliliters of slushy, and he drank 5.55.55, point, 5 milliliters per second.
The graph of the remaining volume of slushy in Mariana's cup (in milliliters) as a function of time (in seconds) is shown below.
Who drank their slushy faster?
Who finished drinking their slushy first?

Answer 1

Answer:Sean and Mariana

Explanation:

Sean is 1 and Mariana is 2

Answer 2

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.
