Quadratic Formula Word Problem
Digital poster for math III with Mr. Kirkland
We can use the quadratic formula to find the x-intercepts!
Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation p=-0.5x + 16x - 12 models the profit of the fundraiser. What's the smallest amount, in dollars, that you can charge and make a profit of at least $100?
Now write the equation in standard form.
Next, use the quadratic equation!
