Answer:
165
Step-by-step explanation:
First we need to find the area of the field, A = r^2 * pi
The radius is 290 / 2 = 145 feet
A = 145 * 145 * 3.14 = <u>66018.5</u> sqr feet
One bag covers 400 sqr feet
Divide the Area by 400 sqr feet to find number of bags needed.
66018.5 / 400 = <u>165</u>
He will need at least 165 bags to cover the field

Answer:
$ 22.6
Step-by-step explanation:
Given that
Price charged for each box of seeds = x
Profit gained from from selling boxes of seeds = p
The equation of profit is modeled as
P(x) = 0.5x² + 36x - 179
As per given information if the fundraisers make a profit of $379 then find the minimum price charged for each box of seed.
Now our above equation becomes
379 = -0.5x² + 36x - 179
Simplifying
379+179 = -0.5x² + 36x
558 = -0.5x² + 36x
0.5x² - 36x + 558 =0
multipying both sides of equation by 2
2(0.5x² - 36x + 558) = 2x0
x² - 72x +1116 = 0
Using quadratic formula we get the following factors
x= 49.4 or x= 22.60
As we can the smalles value is 22.6
So, they can charge 22.6 dollar for each bag of seeds in order to get profit of 379 dollars.
7.25 hour is better because multiply by eleven and its 79.75 which is higher than the on on the table
