  • Question 1 (request help)

    An hourglass is turned over with the top part filled with sand. After 3 minutes, there are 855 mL of sand in the top half. After 10 minutes, there are 750 mL of sand in the top half. Which equation represents this situation?
    • \(\text{y} = 285\text{x}\)
    • \(\text{y} = -10.5\text{x} + 900\)
    • \(\text{y} = -15\text{x} + 900\)
    • \(\text{y} = 75\text{x}\)
