Jenna works as a truck driver. She gets paid $0.40 cents per mile. If she drives 400 miles one way, how much does she get paid for a round trip? Give the rationale and then the answer.
Let's think step by step. First find the total number of miles Jenna drives: 400 miles / way * 2 ways = 800 miles. Then multiply that number by her pay per mile to find her total pay: 800 miles * $0.40 / mile = $320.. The answer is: 320.

A pen is longer than the rubber by 3 centimeters, and shorter than the pencil by 2 centimeters. Considering the pencil is 12 centimeters long, what is the total length of the rubber, the pen, and the pencil altogether? Give the rationale and then the answer.
Let's think step by step. The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = 10 centimeters long. That means the rubber is 10 - 3 = 7 centimeters long. So all accessories are 7 + 10 + 12 = 29 centimeters long altogether.. The answer is: 29.

Madeline wants to plant 20 flowers in her garden. She assumes that about half of the seeds she plants will die before they bloom. However, the flower shop only sells packs of seeds with 25 seeds per pack. Each pack is $5. How much will Madeline spend on seeds to plant 20 flowers? Give the rationale and then the answer.
Let's think step by step. Madeline needs to buy 2 * 20 = 40 seeds to make sure that she will have 20 flowers. Thus, Madeline will need to buy 2 packs of flowers to have at least 40 seeds. Thus, Madeline will spend 2 * 5 = $10 on seeds.. The answer is: 10.
