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?
Let's think: 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.. The answer is: 6.

Bill is laying power cable for a new neighborhood. There are going to be 18 east-west streets that are 2 miles long and 10 north-south streets that are four miles long. It takes 5 miles of cable to electrify 1 mile of street. If cable costs $2000/mile, what is the total cost of cable for the neighborhood?
Let's think: First find the total distance of the east - west streets: 18 streets * 2 miles / street = 36 miles. Then find the total distance of the north - south streets: 10 streets * 4 miles / street = 40 miles. Then add the number of miles from each type of street to find the total distance: 36 miles + 40 miles = 76 miles. Then multiply that number by 5 to find the number of miles of cable needed: 76 miles street * 5 miles cable / mile street = 380 miles of cable. Then multiply that number by the cost of one mile of cable to find the total cost: 380 miles * $2000 / mile = $760,000.. The answer is: 760000.

Judson, Camilo, and Kenny decided to contribute money to paint their house. Judson contributed $500, Kenny contributed 20% more money than Judson, and Camilo contributed $200 more than Kenny. How much was the cost of painting the house?
Let's think: If Judson paid $500, Kenny contributed 20 / 100 * $500 = $100 more than Judson. In total, Kenny contributed $500 + $100 = $600. Kenny and Judson contributed a total of $600 + $500 = $1100. If Camilo contributed $200 more than Kenny, then he contributed $600 + $200 = $800. The total amount of money the three contributed for the house painting is $1100 + $800 = $1900.. The answer is: 1900.

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