Answer this question:A newspaper subscription costs $10/month. If you purchase an annual subscription you obtain a 20% discount on your total bill. How much do you end up paying if you go with the annual subscription?
A year has 12 months. If 1 month costs $10, then a year will cost $12 * 10 = $120 per year without an annual subscription. If the annual subscription has a 20% discount then you would pay $120 * (1 - 20%) = $96 for the annual subscription.
The answer is 96.

Answer this question:Alex is on a cross-country bike trip. After starting this morning, he manages an average speed over flat ground of about 20 miles per hour. Four and a half hours later, the road started to incline upwards enough that he could only manage 12 miles per hour. Two and a half hours later, though, the road declined downhill and was able to mostly coast at 24 miles per hour. Unfortunately, he only got to enjoy this for one and a half hours before he punctured a tire. He had forgotten to pack a repair kit, so he had to walk his bike the rest of the way to the next town. If the next town was 164 miles from where he started this morning, how far did Alex have to walk?
Alex traveled at 20 miles per hour for 4.5 hours, so 20 * 4.5 = 90 miles on flat ground. He traveled 12 miles per hour uphill for 2.5 hours, so 12 * 2.5 = 30 miles uphill. He traveled downhill 24 miles per hour for 1.5 hours = 24 * 1.5 = 36 miles downhill. Before his tire punctured, he traveled 90 + 30 + 36 = 156 miles. So as the next town is 164 miles from where he began, Alex had to walk for 164 - 156 = 8 miles.
The answer is 8.

Answer this question:With one mighty blow, Maria cracked open the pinata, and candies spilled all over the floor. There were 40 red candies, 20 less than three times as many yellow candies as red candies, and half as many blue candies as yellow candies. If Carlos ate all of the yellow candies, how many candies remained?
Three times the number of red candies is 40 * 3 = 120. So, for yellow candies, there were 20 less than 120 candies, or a total of. 120 - 20 = 100 yellow candies. Half as many blue candies as yellow candies is 100 / 2 = 50 blue candies. If Carlos ate all of the yellow candies, then only the 40 red and 50 blue candies remained for a total of 40 + 50 = 90 candies.
The answer is 90.
