In eight years, Mr. Bernard will be 3 times as old as Luke is now.

Question: If Luke is 20, what is 10 years less than their average age?
Answer: If Luke is 20, he will be 20+8 = <<20+8=28>>28 years old in eight years.
In eight years, Mr. Bernard will be 3 times as old as Luke is now, a total of 3*20= <<3*20=60>>60 years old.
Mr. Bernard is now 60-8= <<60-8=52>>52 years old
The sum of their current ages is 52+20 = <<52+20=72>>72
Their average age is 72/2 =<<72/2=36>>36
10 less than their average age is 36-10 = <<36-10=26>>26 years.

Marlon has a gift card for $200. He spent half of it on Monday and one-fourth of the remainder on Tuesday.

Question: How much was left on his gift card?
Answer: Since Marlon spent half of the gift card, then half of it which is $200/2 = $<<200/2=100>>100 remained on Monday.
Then on Tuesday, he spent $100/4 = $<<100/4=25>>25.
Therefore, he has $100 - $25 = $<<100-25=75>>75 left in his gift card.

A family just bought a newborn puppy that must eat a special type of dog food until it is 1 year old. The puppy needs to eat 2 ounces of this special dog food per day during the first 60 days of its life. After that, it needs to eat 4 ounces per day of the special food until it is old enough to eat regular dog food.

Question: If the special dog food is only sold in 5-pound bags, and there are 16 ounces in a pound, how many bags will the family need to buy to feed the puppy until it is old enough to eat regular dog food?
Answer: The puppy will consume 60*2 = <<60*2=120>>120 ounces of the special dog food in the first 60 days.
This leaves 365 - 60 = 305 days where the puppy will consume 4 ounces of food per day, or 305*4 = 1220 ounces of the special food.
Thus, the puppy requires a total of 120 + 1220 = <<120+1220=1340>>1340 ounces of food before it is 1 year old.
Each 5-pound bag contains 5*16 = <<5*16=80>>80 ounces of special dog food.
Therefore, the puppy will need to eat 1340/80 = 16.75 bags of the special dog food, meaning the family will need to buy 17 bags.

A community is building a metal fence. Each fence panel is made of 3 metal sheets, and 2 metal beams. The fence is made of 10 fence panels.

Question: If each sheet is made of 10 metal rods and each metal beam is made of 4 metal rods, how many metal rods does the community need for the fence?
Answer: In each panel, the metal sheets use 3 metal sheets * 10 metal rods = <<3*10=30>>30 metal rods.
In each panel, the metal beams use 2 metal beams * 4 metal rods = <<2*4=8>>8 metal rods.
So each panel uses 30 + 8 = <<30+8=38>>38 metal rods.
The entire fence therefore needs 38 metal rods * 10 fence panels = <<38*10=380>>380 metal rods.

60% of the number of cats in King Henry's kingdom is 60/100*25=<<60/100*25=15>>15 cats
5 less than 60% of the number of cats in King Henry's kingdom is 15-5=<<15-5=10>>10 cats

After 100 new people move into a town, 400 of the original population move out. Every year afterward, the town’s population is halved. After 4 years, the population is 60 people.

Question: Before the new people moved in, how many people lived in the town?
Answer: If the population is halving then at the end of the third year, the population must have been 60 people in the fourth year * 2 = <<60*2=120>>120 people.
In the second year, the population was 120 people in the third year * 2 = <<120*2=240>>240 people.
And in the first year, the population was 240 people in the third year * 2 = <<240*2=480>>480 people.
Additional people moved out in the first year, so accounting for these shows the population was 480 people + 400 people who moved out = <<480+400=880>>880 people.
Then removing the new people shows there were originally 880 people – 100 new people = <<880-100=780>>780 people.

John plays at the arcade for 3 hours. He uses $.50 for every 6 minutes.

Question: How much money did he spend, in dollars?
Answer: He was at the arcade for 3*60=<<3*60=180>>180 minutes
So he put coins in 180/6=<<180/6=30>>30 times
That means he spent 30*.5=$<<30*.5=15>>15

Silvio was running a race that had 4 parts. The total length of the race was 74.5 kilometers. The first part of the race is 15.5 kilometers long. The second and third parts are each 21.5 kilometers long.

Question: How many kilometers is the last part of the race?
Answer: 15.5 + (2 * 21.5) = <<15.5+(2*21.5)=58.5>>58.5 km
74.5 - 58.5 = <<74.5-58.5=16>>16 kilometers
The last part of the race is 16 kilometers.
