Question

Mariana tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds, 148.5 milliliters of slushy remained.
How much slushy was originally in the cup?

Answer 1

9514 1404 393

Answer:

  225 mL

Step-by-step explanation:

The amount Mariana drank was ...

  (4.5 mL/s)×(17 s) = 76.5 mL

The original quantity is that amount added to the amount remaining:

  original amount = amount drunk + amount remaining

  = 76.5 mL +148.5 mL

  original amount = 225 mL
