Answer 1

piece of cake, she got 350ml of water left

Explanation:

lets find out what 10% of 500 is, which is 50

so 20% is 100

we do 10% 3 times, so 50x3=150

500-150=350

it is 350

Answer 2

The student has 350 milliliters of water on the water bottle after she drank 30% of it.

30%=0.30
500 × 0.30=150
500-150=350
