Answer:
Step-by-step explanation:
<u>Wheat flour</u>
- 4 pounds for $8 ⇒ 1 pound for $8/4 = $2
<u>Rye flour</u>
- 5 pounds for $20 ⇒ 1 pound for $20/5 = $4
<u>Equation for total:</u>
String is the hypotenuse
angle is 58 degrees
sine (58) = height / 50
height = 50 * .84805
height =

Legit way is vertex form
easy way is this
x value of vertex in form
f(x)=ax^2+bx+c is -b/2a
the y value is f(x value of vertex)
so
p(x)=-0.5x^2+40x-300
x value of vertex is -40/(2*-0.5)=-40/-1=40
max profit selling 40 per week
profit would be 500
When I worked it
out, I got this.
30 tens=300
3 tens= 30
3 tenths = .3
So 300-30.3= 269.7
