Answer this question:Mr. Johnson has a prescription with enough pills for 30 days. After four-fifths of the days, he has 12 pills left. How many pills is Mr. Johnson supposed to take a day if he takes the same dose daily?
Mr. Johnson has been taking the pills for 30 * 4 / 5 = 24 days. He has 30 - 24 = 6 days left to finish the pills. Thus, Mr. Johnson is supposed to take 12 / 6 = 2 pills a day.

Answer this question:My cat's empty bowl weighs 420 grams. If I give my cat 60 grams per day and I always fill her bowl every 3 days, how much does her bowl weigh if after I ended up refilling her empty bowl she only ate 14 grams?
If I give my cat 60 grams per day and I fill it to last 3 days, then I put a total of 60 * 3 = 180 grams into her bowl. If the empty bowl weighs 420 grams and I put 180 grams the total weight is = 420 + 180 = 600 grams. If my cat only ate 14 grams then the bowl right now weighs 600 - 14 = 586 grams.
The answer is 586.

Answer this question:Axel bought an aquarium that was marked down 50% from an original price of $120. But he also paid additional sales tax equal to 5% of the reduced price. What was the total cost of the aquarium?
The aquarium was bought for $120 x 50 / 100 = $60 less. So the marked down price of the aquarium was $120 - $60 = $60. Axel paid $60 x 5 / 100 = $3 additional for the sales tax. Therefore, the total cost of the aquarium was $60 + $3 = $63.
The answer is 63.
