Mariana tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.54.54, point, 5 milliliters per second. After 171717 seconds, 148.5148.5148, point, 5 milliliters of slushy remained. How much slushy was originally in the cup?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
