Anika has 4 more than twice the number of pencils as Reeta. If Reeta has 20 pencils, how many pencils do the two have together? Give the rationale and then the answer.
Let's think step by step. If Reeta has 20 pencils, then twice that number is 2 * 20 = 40 pencils. Anika has 4 more than twice the number of pencils as Reeta, which means she has 40 + 4 = 44 pencils. Together, the two have 44 + 20 = 64 pencils.. The answer is: 64.

Jackson is buying school supplies for his third grade class, which has 30 students. Each student needs 5 pens, 3 notebooks, 1 binder and 2 highlighters. Pens cost $0.50, notebooks cost $1.25, binders cost $4.25, and highlighters cost $0.75. If Jackson gets a $100 teacher discount, how much does he spend on school supplies? Give the rationale and then the answer.
Let's think step by step. First calculate the cost of the pens for one student by multiplying the number of pens by the cost per pen: 5 pens * $0.50 / pen = $2.50. Then calculate the cost of the notebooks for one student by multiplying the number of notebooks by the cost per notebook: 3 notebooks * $1.25 / notebook = $3.75. Then calculate the cost of the highlighters for one student by multiplying the number of highlighters by the cost per highlighters: 2 highlighters * $0.75 / highlighter = $1.50. Now add the cost of all the different supplies to find the total cost for one student: $2.50 + $3.75 + $1.50 + $4.25 = $12.00. Now multiply the cost per student by the number of students to find the total cost before the discount: 30 students * $12.00 / student = $360.00. Now subtract the teacher discount to find the final cost: $360.00 - $100.00 = $260.00.. The answer is: 260.

Tom has a quarter as much money as Nataly. Nataly has three times as much money as Raquel. How much money do Tom, Raquel, and Nataly have combined if Raquel has $40? Give the rationale and then the answer.
Let's think step by step. If Nataly has 3 times as much money as Raquel, she has 3 * $40 = $120. Tom has 1 / 4 as much money as Nataly, so he has 1 / 4 * $120 = $30. Combined, the three have $30 + $120 + $40 = $190.. The answer is: 190.
