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= -0.53 +25x - 120
models the profit of the fundraiser. What's the
smallest amount, in dollars, that you can charge and make a profit of at least $105?

Answer 1

$9.03

If you want smallest amount it dollars, you have to go with $9. However, this will only give you a profit of $104.47

Explanation:

p = -0.53 +25x - 120

105 = -0.53 +25x - 120

225.53 = 25x

x = 9.0212

Check work:

105 = -0.53 +25(9.02) - 120

105 ≠ 104.97

Since $9.02 doesn't equal $105 profit, let's add a penny to make it $9.03.

105 = -0.53 +25(9.03) - 120

105 ≠ 105.22

If you charge $9.03 for each box you will make a profit of at least $105.

Round to smallest amount in dollars:

105 = -0.53 +25(9) - 120

105 ≠ 104.47
