A farmer owns a hog that recently gave birth to 6 piglets. If the farmer raises the piglets until they are fully grown, he can sell the fully grown pig for $300. Each piglet must grow for at least 12 months before it is large enough to be sold. It costs the farmer $10 per month to feed each animal until it is sold.

Question: If the farmer sells 3 pigs after 12 months, and the remaining 3 pigs after 16 months, how much profit did he earn in total (after deducting the cost of food)?
Answer: The 3 pigs that are sold after 12 months will cost the farmer 12*10*3 = $<<12*10*3=360>>360 in food costs.
The 3 pigs that are sold after 16 months will cost the farmer 16*10*3 = $<<16*10*3=480>>480 in food costs.
Thus, the total food cost to raise the 6 piglets was 360 + 480 = $<<360+480=840>>840.
Next, selling the 6 fully grown pigs will earn the farmer 6*300 = $<<6*300=1800>>1800 in revenue.
Therefore, the earn the farmer 1800 - 840 = $<<1800-840=960>>960 in profit from these sales.

A teacher asked Adelaide, Ephraim, and Kolton to buy ducks and monitor their growth patterns and features for their science class. Adelaide bought twice the number of ducks that Ephraim bought, while Ephraim bought 45 fewer ducks than Kolton.

Question: If Adelaide bought 30 ducks, what's the average number of ducks the three bought?
Answer: If Adelaide bought 30 ducks, Ephraim bought 30 ducks / 2 = <<30/2=15>>15 ducks.
Since Ephraim bought 45 fewer ducks than Kolton, Kolton bought 45 ducks + 15 ducks = <<45+15=60>>60 ducks
The total number of ducks the three bought is 60 ducks + 15 ducks + 30 ducks = <<60+15+30=105>>105 ducks
The average number of ducks each bought is 105 ducks / 3 people = <<105/3=35>>35 ducks/person

In total, Susy finishes the three weeks with 140+20+10 = <<140+20+10=170>>170 total followers.
After one week, Sarah has 50+90 = <<50+90=140>>140 followers.
After the second week, Sarah gains 90/3 = <<90/3=30>>30 followers.
After the third week, Sarah gains 30/3 = <<30/3=10>>10 followers.
So, Sarah finishes the three weeks with 140+30+10 = <<140+30+10=180>>180 total followers.
Thus, Sarah is the girl with the most total followers with a total of 180.

Cole wants to fence his backyard on three sides. His backyard is 9 feet along the sides and 18 feet along the back. The neighbor behind him agreed to pay for half of their shared side of his fence, and the neighbor on his left agreed to pay for a third of their shared side. Fencing costs $3 per foot.

Question: How much does Cole have to pay for the fence?
Answer: Cole has to pay 3 * 9 = $<<3*9=27>>27 for one side of the side fence.
For the shared left fence, he has to pay two-thirds of 27, so he has to pay 27 * 2 / 3 = $<<27*2/3=18>>18.
The shared back fence will cost 3 * 18 = $<<3*18=54>>54.
He has to pay for half the back fence, so it will cost 54 / 2 = $<<54/2=27>>27.
Thus, Cole has to pay 18 + 27 + 27 = $<<18+27+27=72>>72 for the fence.

An auto shop buys tires to replace all the tires on every customer’s car. They buy the tires as soon as cars are brought into the shop. There are four cars in the shop already, and another six customers come into the shop throughout the week. Some of the customers decide they don't want any of the tires changing, and two customers decide they only want half the tires changing. They had no tires in stock at the start of the week.

Question: If the shop has 20 tires left at the end of the week, how many customers decided they did not want their tires changing?
Answer: A total of 4 + 6 = <<4+6=10>>10 cars are in the shop throughout the week.
This means the shop buys 10 cars * 4 tires = <<10*4=40>>40 tires.
For each of the customers that only want half the tires changing, there are 4 tires * 0.5 = <<4*0.5=2>>2 tires left over.
Two of the customers only want half the tires changing, so there are 2 tires * 2 cars = <<2*2=4>>4 tires left over from these customers.
Out of the remaining tires, there are 20 – 4 = <<20-4=16>>16 tires left from customers who don't want their tires changing.
So in total, there were 16 tires / 4 tires per customer = <<16/4=4>>4 customers who did not want their tires changing.

She received $15.00 from the cashback app and has a $25.00 mail-in rebate for a total of 15+25 = $<<15+25=40.00>>40.00 discounts
She spent $150.00 for the medicine and has $40.00 worth of discounts so the medicine will cost 150-40 = $<<150-40=110.00>>110.00

The sum of Mario and Maria's ages now is 7. Mario is 1 year older than Maria.

Question: How old is Mario?
Answer: If x is Maria's age, then Mario's age is x + 1.
The equation that represents the sum of their ages is x + x + 1 = 7.
By combining like terms, the equation becomes 2x = 6.
Hence, the value of x which represents the age of Maria is 6/2=<<6/2=3>>3.
So Mariu is 3 + 1 = <<3+1=4>>4 years old.
