Linear modeling project — Homework
Complete this mini modeling project. Show the equation, both calculations, and your check table.
- 1.A bakery starts the day with 40 muffins and sells about 6 per hour. Write the model (x = hours, y = muffins left). Is this rate positive or negative? Why?
- 2.Using y = -6x + 40, how many muffins are left after 3 hours?
- 3.Using y = -6x + 40, after how many hours are there only 4 muffins left?
- 4.Make a 3-row check table (x = 0, 1, 2) for y = -6x + 40 and confirm it matches the rate.
- 5.Pick your own real quantity that changes at a steady rate (savings, gas in a tank, book pages read). Write its equation, and use it to answer one forward question and one backward question.
