# 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!

Now solve!

Therefore, to make a profit of $100, the smallest amount you can charge for each box of flower seeds is $10.34.
