Last week, Leonardo's hamster drank 25 mL of water. This week he drank 15 mL of water. By what percent did the hamster’s intake of water decrease?

40%

Step-by-step explanation:

It went down by 10 ml.

40% of 25 is 10, so te answer would be 40%

60%

Step-by-step explanation:

Part/whole method:

15·100=1,500

1,500÷25=60

15 is 60% of 25

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
