Step-by-step explanation:
Answer:
c. 34
Step-by-step explanation:
1) Add all the given prices on each day.
= 42.80 + 64.20 + 74.90
= 181.90
2) Set up an equation since we do not know how many magazine subscriptions she sold, but we know how much money she made.
Let x = number of magazine subscriptions sold
5.35x = 181.90
x =
x = 34
The answer is 54 square units.
let the vertex in quadrant I be (x,y)
<span>then the vertex in quadratnt II is (-x,y) </span>
<span>base of the rectangle = 2x </span>
<span>height of the rectangle = y </span>
<span>Area = xy </span>
<span>= x(27 - x</span>²<span>) </span>
<span>= -x</span>³<span> + 27x </span>
<span>d(area)/dx = 3x</span>²<span> - 27 </span><span>= 0 for a maximum of area </span>
<span>3x</span>²<span> = 3 x 3</span>² = <span>27 </span>
<span>x</span>²<span> = 9 </span>
<span>x = ±3 </span>
<span>y = 27-9 = 18 </span>
So, the largest area = 3 x 18 = 54 square units
