The time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Step-by-step explanation:
Given that,
The kitchen sink can fill in: 6 mins
The sink can drain in: 10 mins
We have to find the time to fill the sink if Blake forgets to put in the stopper. For that,
Lets say, the full tank = 1
Filling rate = 
Drainage rate = 
Hence, the time to fill the tank would be:
(Multiply by LCM)
x = 15
Hence, the time to fill the sink if Blake forgets to put in the stopper would be 15 mins.

Getting it wrong on Khan Academy hah
In this question, we're trying to find the cost of feeding the cats for a year.
We know that we use 12 cans to feed the cats
We also know that each can costs $0.60
To find how much the cafeteria spent on the cats, we need to see how much 12 cans cost, and multiply that by 52 to get our yearly cost
Solve:
12 · 0.60 = 7.2
12 cans = $7.20
Now multiply 7.20 by 52 to get our minimum yearly cost for the cats.
52 · 7.20 = 374.4
This means that it costs $374.4 to feed the cats for a year.
Answer
$374.40
