Looking at the graph, we'll notice that there is a local maximum at x=0 and it looks similar on both sides of the y axis, therefore making it symmetric around the y axis given the options
The answer is in the image
Her business will break even when she contains sold 1740 bottles of her lotion.
<h3>
How many bottles of lotion must she make and sell before her business breaks even?</h3>
Given: She invests $15,225 in equipment to manufacture and package her lotion each bottle costs $3.25 to manufacture and sells for $12.
"Break even" occurs when Revenue = Costs.
($12/bottle)x = $15225 + ($3.25)x
Simplifying the above equation, we get
$8.75x = $15225
Diving both sides of the equation by 8.75, we get
$8.75x/8.75 = $15225/8.75
x = 1740 bottles
Therefore, the value of x = 1740 bottles.
Her business will break even when she contains sold 1740 bottles of her lotion.
Therefore, the correct answer is option b. 1740 bottles.

Using the product rule
xCos(y)dy/dx + sin(y) + ycos(x)+sin(x)dy/dx = 0
xcosydy/dx + sin(x)dy/dx = -sin(y) - ycos(x)
(xcos(y) + sin(x))dy/dx = -sin(y) - ycos(x)
dy/dx = [-sin(y) - ycos(x)]/ {xcos(y) + sin(x)}
-5/8 or -8/5 so that is tgd answer yeah
