What is the percentage difference in their tail size, expressed as a percentage of the Western rattlesnake's tail size? How many segments are in the Western rattlesnake's tail? ** First find the difference in size between the two kinds of snake tail: 8 segments - 6 segments = <<8-6=2>>2 segments How many segments are in the Western rattlesnak's tail? ** Then divide that amount by the size of the Western rattlesnake's tail and multiply by 100% to express the answer as a percentage: 2 segments / 8 segments * 100% = 25% #### 25 Job is a farmer who rears cattle and grows crops. In total he has 150 hectares of land. 25 hectares are occupied by his house and farm machinery, and 15 hectares have been reserved for future expansion. 40 hectares are dedicated to rearing cattle. Assuming the rest of his land is used for crops, how many hectares of land does Job use for crop production? How many hectares of land does Job use for non-crop purposes? ** Job uses 25 + 15 + 40 = <<25+15+40=80>>80 hectares of land for non-crop purposes.

His coworker Paula takes 3/5 of this time to arrive by bus at work. If Luke takes a bike ride back home every day, 5 times slower than the bus, and Paula takes the bus back home, calculate the total amount of time, in minutes, they take traveling from home to work and back each day. How many minutes does Paula take to travel from home to work? ** When Luke takes the 70-minute bus to work, his coworker Paula takes 3/5*70 = <<70*3/5=42>>42 minutes to travel from home to work.

They are stored in boxes and inside the boxes, they are stacked 5 rows high with 4 cups in each row. Of the 26 boxes in her attic, 6 of the boxes contain pans, half of the remaining boxes contain decorations, and the rest of the boxes contain her teacups. Samuel breaks 2 of the cups every time he picks up one of the boxes. By the time Samuel has taken all of the teacups out of the boxes, how many teacups are left? How many boxes are either decorations or teacups? ** Taking the boxes of pans out of the total attic boxes shows that 26 boxes – 6 boxes of pans = 20 boxes are either decorations or teacups. How many boxes are teacups? ** Since half of these boxes are decorations, the other half must be made up of 20 boxes / 2 = <<20/2=10>>10 boxes of teacups. How many teacups are in each box? ** Each box of cups initially has 5 rows x 4 cups = <<5*4=20>>20 teacups inside. How many teacups are in each box after Samuel breaks 2 cups? ** Samuel breaks cups each time he picks up a box, which means each box now contains 20 – 2 = <<20-2=18>>18 teacups. How many teacups are left? ** Therefore, there are 10 boxes * 18 teacups = <<10*18=180>>180 teacups left. #### 180 Mario's salary increased by 40% to $4000 this year.
