[Question]: Rikki is writing and selling poetry. He sells his poems for $.01 a word. He can write 25 words of poetry in 5 minutes. If he has 2 hours to write poetry, how much can he expect to earn?
[Answer]: He will write for 120 hours because 2 x 60 = 120. He will write for 24 units of five minutes each because 120 / 5 = 24. He can write 600 words because 24 x 25 = 600. He can earn $6 because 600 x .01 = 6.
So the answer is 6.

[Question]: Everett built a rectangular concrete patio that was four times as long as it was wide. If the perimeter of the patio was 100 feet, what was the length of the patio, in feet?
[Answer]: Let's make "x" be the width of the patio. Then the length of the patio would be 4 * x. And the perimeter of the patio would be the sum of all four sides, or x + (4 * x) + x + (4 * x) = 100 feet. This simplifies to 10x = 100 feet. And the width of the patio x = 10 feet. And the length of the patio is 4 * x = 4 * 10 = 40 feet.
So the answer is 40.

[Question]: Tom decides to buy some shirts from his favorite fandoms because there is a sale on his favorite website. He buys 5 t-shirts from each of his 4 favorite fandoms. The shirts normally cost $15 each but there is a 20% off sale. The order qualified for free shipping but he still needed to pay 10% tax. How much did he pay?
[Answer]:
He bought 5 * 4 = 20 shirts. The discount saves him 15 * .2 = $3 per shirt. So each shirt cost 15 - 3 = $12. So the total order cost 20 * 12 = $240. Tax added 240 * .1 = $24. So he paid 240 + 24 = $264.
So the answer is 264.
