A small juice company spends $1200 per day on business expenses plus $1.10 per bottle of juice them make. They charge $2.50 for
Greeley [361]
Cost price per bottle of juice = $1.10 
Selling price per bottle of juice = $2.50 
Profit per bottle of juice = $2.50 - $1.10 = $ 1.40 
Let B be the number of bottles needed to sell in one day in order to equal its daily costs. 
$1200 = $1.40B 
857.14285714285714 = B 
858 = B (round off to the nearest bottle) 

The company must sell 858 bottles of juice in one day in order to equal its daily cost. 

Hope this helps! =)

The coordinates of the vertices of △JKL are J(3, 4), K(3, 1) , and L(1, 1) . The coordinates of the vertices of △J′K′L′ are J′(−
timurjin [86]

The <em><u>correct answer</u></em> is:

A 180° rotation followed by a translation 1 unit down.

Explanation:

The points are mapped as follows:

J(3, 4)→J'(-3, -5)

K(3, 1)→K'(-3, -2)

L(1, 1)→L'(-1, -2)

A 180° rotation maps a point (x, y) to (-x, -y).  This would map

J(3, 4)→(-3, -4)

K(3, 1)→(-3, -1)

L(1, 1)→(-1, -1)

The difference between these points and the image points are that each y-coordinate of the image is 1 lower than these.  This means a translation 1 unit down would result in the image points.
