Answer:
6p^2-24p+22
Step-by-step explanation:
when is 9 = 15.2 - 0.537x
9 = 15.2 - 0.537x
-15.2 -15.2 subtract 15.2 from both sides
-6.2 = -0.537x
/-0.537 /-0.537 divide -0.537 from both sides
11.55 = x or 12 feet round to nearest whole foot
In this question, <span>q is the number of buggies the company can sell in a month if the price is $p per buggy. The revenue should be number of buggies sold(q) multiplied by the price(p). The equation would be:
revenue= p * q
revenue= p * (-4p + 616)= -4p^2 + 616p
The maximum revenue should be in the peak of the graph. The calculation would be:
</span>-4p^2 + 616p
-4*2 p^2-1 + 616*1 p^1-1=0
<span>-8p + 616=0
8p= 616
p=77
Put p=77 in the revenue equation would result
</span>revenue= -4p^2 + 616p
revenue= -4(77^2) + 616(77) = -23716 + 47432= $23716
(3y+40)+(3x-70)=180
3y+3x-30=180
3y+3x=210
3(y+x)=210
y+x=70
x=70-y
meanwhile 180-120=x therefore x=60
therefore
60=70-y y=10
so x=60 y=10
Choice A : 3.49/25 = 0.139 rounds to 14 cents per oz
