1) Jane, Kayla and Mandelite want to give their friend nadine a potted plant for her birthday. Jane spends 35$ on a pot, Kayla spends 3$ on a potting soil and mandelite buys a plant for 24$. If jane, Kayla and mandelite want to share their costs equally then who should give whom how much? Explain!
2) The country of taxalot has a different method of taxing income. If you make 1000$ per year your tax is 1%. For each additional 1000$ you make per year, your tax rate goes up 1%, so that, for example, if you made 24,000$ per year you would pay 24% in taxes. If you could set your salary anywhere between 0$ and 100,000$, what would you want it to be and why?
3)Ms. Jones, an elementary school teacher, has 24 students. Every day she picks two students to be her "special helpers" for the day. How many pairs of students are there in the class? If the school year is 190 days long, will there be enough days for every pair of children to be the "special helpers"? (notice that the problems asks about every pair of children, not every individual child.)
I would really appreciate it. Thank you.
