Question: Parker wants to find out what the average percentage of kernels that pop in a bag is. In the first bag he makes, 60 kernels pop and the bag has 75 kernels. In the second bag, 42 kernels pop and there are 50 in the bag. In the final bag, 82 kernels pop and the bag has 100 kernels.
Answer: In the first bag the proportion that pops is .8 because 60 / 75 = .8. In the second bag the proportion that pops is .84 because 42 / 50 = .84. In the third bag the proportion that pops is .82 because 82 / 100 = .82. The proportions totals 2.46 because .8 + . 84 + .82 = 2.46. The average proportion is .82 because 2.46 / 3 = .82. The average percentage is 82 because .82 x 100 = 82. The answer is 82.

He found a nice apartment next to his school, the owner asks Jeff to pay $300 each month, Jeff agreed, and for the first 3 years everything went fine, but then the owner wanted to raise the price for each month to $350. Jeff agreed again and continued paying until he graduated. How much did Jeff end up paying for the apartment throughout the 5 years?
[Answer]
At first Jeff paid, $300 / month x 12 months = $3,600 / year. He paid $3,600 / year x 3 years = $10,800 the firsts 3 years. The final 2 years he paid $350 / month x 12 months = $4,200 / year. He paid $4,200 / year x 2 years = $8,400 the last 2 years. He paid the owner $10,800 + $8,400 = $19,200 in total. The answer is 19200.
